I had taken my truck to a mechanic called XXXX in XXXX XX/XX/XXXX, they were suppose to do a rebuilt head gasket to my vehicle for {$1500.00} which I paid by credit card. 
The moment I picked up the truck it was still smoking white smoke which means theres still some coolant in the oil pan, when I drive back to the mechanic and complained, XXXX the owner told me to just let it run for a couple days to get the smoke to stop. Not True!! When he told me this, I couldnt believe when you paid to have a problem fixed and when you pick up your vehicle and the probe still exist, this was NOT fixed at all! Why I know this is because I took my truck to a Professional machine shop that works onbhead gaskets because they know how to mill a head gasket and work on head gasket many times. I took this to XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX, XXXX Illinois XXXX XXXX on XX/XX/XXXX tonhave my truck inspected by the owner XXXX XXXX. 
He clearly proved to me that XXXX never rebuilt my head gasket at all and explain and showed me proof, I was so mad after I felt this mechanic took me for a ride and scammed me for my money. After seeing many other XXXX reviews and listening to my wife about filing a dispute with Fifth Third bank for the amount of what I paid {$1500.00} for No rebuilding my. Head gasket at all. Now that I did this and I did get a letter from Fifth Third bank that the dispute investigation was approved and final, and then after a few weeks that went by and me not having any money but {$3.00} in my account, I finally worked a job and deposited a check for {$1100.00} on XX/XX/XXXX and then all of sudden Monday XX/XX/XXXX I was negative {$440.00} which they reversed the charges that fifth third bank finalized and approve that money they gave back to me, and when I called the bank to have them explain that to me, hey told me that the mechanic shop said they did the work on my car and I said they only said they worked on my car and thats all??? And Im like anyone can say anything kind of lie but when I sent in 3 copies of what proof I had with the machine shop inspector to fifth third bank, why would this bank just believe this mechanic shop when they were clearly proven wrong and then my own bank which Im the customer and not the mechanic shop and take and remove my money from my account, and then at first after I deposited that check for {$1100.00} they told me and sent me a letter stating that that check from my boss had insufficient funds which she did and that was lie. Which is kind of funny that ever since I only had {$3.00} in my account and when I finally did a deposit, isnt it funny now they are keeping my {$1100.00} from that check I deposited??? Kind of funny I think, which means they only took my money cause they decided that they werent going to lose any money for sure so lets take it from there customer XXXX XXXX account and at least we wont be short money and they XXXX me again. When this mechanic shop is the one that took my money and Fifth Third bank is letting them get away with my money. And when I talk to XXXX the executive assistant for the bank President, she tells me that the dispute Dept closed and finalized my account on XX/XX/XXXX and Im like why when thats the day your dispute Dept ask me for that proof again from the machine shop I took my truck to have inspected and it was faxed over that same day at Fifth Third bank in XXXX Illinois on XXXX XXXX and on Tuesday XX/XX/XXXX my banker at fifth third bank called dispute Dept to confirm they received my proof again and they did, so I ask XXXX to listen to the phone call on Monday XX/XX/XXXX when the lady in disputes ask me to send her that other part of the letter that showed the inspectors notes that shows this mechanic shop never worked on my truck and I said why would the dispute Dept close that account when I sent proof??? Something crooked is going on here and I believe Fifth third bank is doing me wrong and the trail of proof is there when they tell me one thing and then do something else to me. XXXX from fifth third bank explain to me today Friday XX/XX/XXXX that she will follow up on Monday XX/XX/XXXX about why they would close this account when I did what they wanted me to do. She called the dispute Dept and they did confirmed with her that I did send proof and faxed it over that Monday XX/XX/XXXX like I said I did. I told her I just want my money back on my account and give me what rightfully mine. 
I dont want to be with this bank anymore because of all the run around they do to there customers. You dont treat a customer like the way they treated me and they treated me like a victim which Im a 3 time US XXXX war veteran that has been XXXX 9times in the 3 wars Ive been in and to be treated like this is a disgrace to me as a XXXX XXXX veteran recipient from President Obama. Fifth Third bank has to understand if a merchant has a complaint or feel they have a reason to ask for there money back, the customers bank should have to call or send an email or letter to the customer explaining what the merchant stated and have that merchant prove and show proper evidence that they did work on that vehicle and then Fifth Third bank has to explain to the customer that they will remove that money back, but what this bank does should be against the law by removing money from the customers account without proper notice to the customer of that bank. The customer is getting stabbed by there own bank and the mechanic shop is getting away with the customers money and this bank is stealing my money from my account and even after Fifth Third bank approved that money given back to me In the first place. 
Im contacting my attorney to sue Fifth Third bank for removing money without proper notification to me as there customer after me sending them proof and then they closed my account the same day with telling me.
