Product: Checking or savings account

Respected Sir Mam I opened checking account in Wells Fargo bank in XXXX. In XXXX I started facing issues with my account. Any transaction I used to do the bank used to charge me overdraft fees. In XXXX XXXX month I remember I had a word with the banker and that time I had all the transaction details with me with all the figures. I showed the banker each and every transaction details step by step with all the figures of each and every transaction. This was the bankers wordings to me she dont know why the bank has charged you so many over draft fees for no reason when you had sufficient balance for the transaction to get approved. She said she will check on this and get back to me. For no reason the bank kept on adding overdraft fees upon fees. XXXX and mid XXXX I did not realize how much I must have paid in overdraft fees to the bank unnecessarily. 
I never took a loan from the bank. My limit to over draw the account was {$300.00}. My account was shown negative balance of {$1100.00}. In XXXX I had the proof of the bank guilt. I received a letter from the bank that all the charges had been waived off and the account has been closed by the bank. Along with that offer for new checking account option was given. 
One simple question. If I was a defaulter then why the bank opened my new checking account. Why did they allow the new checking account to activate overdraft services? They know if I am not a good person then why will they risk again on me and give me such services? 
In the new account I had deposit money so many times in these couple of years then why the bank did not debited the money earlier for my previous account and why they waited till XXXX? 
XXXX/ XXXX I was able to give proper reply to the bank with all the transaction details in my hand and bank was not able to reply me that time. But now 5 years ago transaction details how can I remember? The bank could have immediately debited the money when I opened this new checking account with {$14000.00}. Why they did not debited in the beginning and waited for couple of years? Now I can not prove my honesty as I dont have any evident to justify my honesty. 
Now whatever the bank will tell all will believe. 

I had complaint about my missing money from my new checking account of {$1500.00}. 
I had a word with the banker and there were different stories all together. 
XXXX ) my claim has been closed and the bank is not liable to pay you back the money as the atm was not showing any extra money of my deposit. The atm was functioning properly and had no issues at all and they verified it from the branch as well. So they did not find any of my deposit money. The case is closed. 
XXXX ) I had collection charges from my previous account and the deposited money from my new account which earlier it was missing and now all of sudden the bank has settled the previous collection charges with my recently deposited money. 

I mentioned the banker that the bank had waived of all the charges as I was able to prove the bank guilty that time. 
The banker replied that the system has not notified us with this information. 
If the system is not showing then then there is a major problem with Wells Fargo banking system. 
I can prove it that there is problem with Wells Fargo system. 
I can prove in front of all that on XXXX the bank has closed my account? 
But on XXXX I did couple of transaction with my closed checking account and it allowed me and also was approved. 
My cash deposit money was not shown on their banking system? 
My transaction details of XXXX is not shown on their system? 
Like this many proof I can show that anything is possible with wells Fargo banking system. 
So if a note is missing related to my previous account if waiving of my fees is not a big deal. 
My only concern is why in XXXX the bank took action for my XXXX account? Why this action the bank failed to take in early stage as I opened this account? Why the bank did not mention this collection charges on my credit profile? Why all of sudden this collection charges arise? 
This is a nice way of hiding their guilt and a good way of escaping from all the charges and to divert the mind from our on going problems.
