Product: Debt collection

Our company had a commercial fuel card account with XXXX XXXX ( aka XXXX XXXX ) in XXXX Ga. We closed the account around XXXX of this year due to nonstop bogus charges on our invoices. They would automatically sign us up for programs that we did n't want or make up new fees and we would have to call to get them removed and credited back to our account. For example, on XX/XX/XXXX we were charged {$430.00} for high risk credit fee. This was not triggered by a late payment. When we called to dispute the charge, we were told that their computers crashed and to call back the next day to have it removed and we did. They also swapped over to a new online system around the beginning of the year which delayed them sending invoices and they sent a notice ( included in attachment ) stating that they would extend due dates because we could not pay the bill online until their system was fully functional. We then mailed a check on XX/XX/XXXX in the amount of {$25000.00}. Due date was XX/XX/XXXX. As of XX/XX/XXXX the check had not cleared and we were charged {$3600.00} late fee, XXXX interest, and they signed us up for a program called clean advantage for {$360.00}. Again we called and they agreed to remove and credit these charges on the next billing cycle along with {$5.00} bonus fee, {$15.00} check fee, and {$4400.00} minimum program admin fee. The last invoice received billing date of XX/XX/XXXX, all charges were removed except for " clean advantage '' fee of {$410.00} and fuel charges of {$440.00}. I called to ask what clean advantage was why we keep getting billed for it. His response was " let me email you the information so you can look at it ''. After looking at the email ( included in attachment ) while he was on the phone I learned that this program is designed to fund projects to help reduce C02 emissions by planting trees and develop recreational space for people to enjoy. I asked him to remove the charge that we never asked for. He said ok and I was given reference # XXXX on XX/XX/XXXX.  This was the last invoice received from this company and the account was deactivated. After hours spent on the phone correcting similar issues each billing cycle, we determined that this company is unethical in its business practices. XXXX XXXX XXXX have been flooding with complaints about this company with similar issues. We signed up with a new fuel card company and have had ZERO issues or surprise fees. 6 months have passed and we received a call from a collection agency on XX/XX/XXXX trying to collect a debt from universal fleet card. The amount is for {$1500.00}. We have no clue what this is for and when we asked the collection agency to send a breakdown of charges their response was " no going to happen ''. This person was very rude as well. Then we received a letter from XXXX XXXX collection agency dated XX/XX/XXXX collecting debt for same amount. I assume these are the same people that called. We do not owe this debt. Our last invoice was paid on XX/XX/XXXX and we have n't received anything from them since. I called XXXX XXXX on XX/XX/XXXX to get a breakdown of the {$1500.00} but they were not willing to help me and said that I need to go through the collection agency with any questions.
