Product: Checking or savings account

I created an account with XXXX XXXX XXXX ( XXXX ) so that I could purchase a vehicle to rebuild into a race car. I paid {$200.00} to create a bidding account which stated I could start bidding right away. After I created the account I tried to bid online, but it would not let me. I assumed that it needed a day to begin bidding, so I waited till the following day, yet I was still unable to bid so I called the company and was told that Colorado does not allow their citizens to bid online for cars. I was told that I needed to use a broker and was directed to XXXX XXXX which was associated with XXXX. I was refunded my money but told to create an account with XXXX XXXX which was {$400.00}, and I could bid right away. I created the account, gave my {$400.00} and started bidding. I won a XX/XX/XXXX XXXX for {$160.00}, but when I called in to go pick up the vehicle I was told that I won the preliminary bid not the online bid. I asked what I needed to do to actually win the car and was told to bid online but I needed to pay a {$200.00} fee to bid. I paid the fee and started bidding. I won the car this time at {$1600.00} and called the auction house which was down the street from where I was at, so that I could see what to do so I could come pick up the car. The auction house said I needed to contact my broker and get that information. I called XXXX XXXX and was told that I had to wait to see if the seller of the car would accept {$1600.00}, because there was a reserve on the bid and I did not meet it. I said they should put that on the website because I wouldn't bid on a vehicle with a reserve as it is too complicated. I asked if this was going to take long and XXXX XXXX said it can take up to five days. I asked if this would cost more money and was told {$100.00} a day for storage plus {$50.00} a day for administrative fees and could get upwards of {$800.00} more plus other fees and charges. I said these are hidden fees and I won't do that I said I do not want to accept the bid and withdraw my bid and reject the owners decision. it took a few hours but I was able to convince the supervisor of my decision and my money was refunded. The supervisor at XXXX XXXX said that bookkeeping may try to take the money at a later date, so I should contact my bank. 
I contacted the dispute department at Chase bank and informed them of the above. I was assured that my money would be protected, and they can see where my money was refunded by XXXX XXXX. I asked if there was a way to ensure that XXXX XXXX could not take money out of my account and was told by Chase that I could not stop the withdrawal. Approximately two weeks later I awoke to see a bill posted that took all my money from my checking account, I then transferred money from my savings account to cover the bill. I fell back asleep for three hours when I awoke again I saw that XXXX XXXX took the {$400.00} back out of my account. I called Chase and was told there was nothing hat could be done. I asked for a supervisor and when he came on he said I should be more responsible about how I use my debit card. I said I was assured that my debit card is safe to use and unauthorized charges would be taken care of. The Chase supervisor said that once I give my card number the merchant can use it whenever they want. I asked so if I buy a burger at XXXX for {$5.00} and six months later they take {$500.00} thats an authorized transaction because I gave them the card number. The Chase supervisor said yes, once my card number is given, then it gives them permission to take money whenever they want. I said I want a higher supervisor and was told there isn't one then the supervisor hung up. Chase put the money back in my account, and I closed my account with Chase immediately. 
Approximately ( 45 ) days after I closed my Chase account, I was contacted by Chase and told they were going to open up my account again and withdraw the money, thereby putting the account negative. I said I do not give them permission to do that and again began another argument with Chase on this dispute. I said I wanted a supervisor and was told that I would be contacted. About two hours later the supervisor called and said I was going to be held accountable for the money. I said I cancelled the sale and did not give them permission to withdraw money two weeks later, but Chase said I was not being responsible with my card. The Chase supervisor said they would call XXXX XXXX with me on the line and tell them I did not authorize it. We contacted XXXX XXXX on a three way, and I recorded the conversation. I explained that I did not authorize the transaction and that I was refunded my money. Then I explained the above to the representative, he admitted they took the money weeks after I cancelled the order but they wanted that money and said I owe another {$1200.00}. I explained I will sue and they said go ahead. The Chase supervisor said I was still being held liable for the money even though I cancelled and it was taken out weeks after I cancelled. I told the Chase Supervisor tat I would initiate suit if they tried to reopen my account without my permission. They said go ahead.
