XXXX XXXX Target Account # XXXX This is about my request to Target for them to remove a collection from my credit report. I wrote a dispute letter to the three credit bureaus requesting they remove the debt from my credit report since it was not mine. They responded by updating my credit report as accurate with the exception that Target put that I had made a recent payment on the account which I had not. I wrote the three bureaus again requesting proof of the recent payment and they responded with an update to my credit report by changing the recent payment and adding a date that was from 2018. 
I filed a complaint with the CFPB asking for this account to be removed from my credit report due to inaccurate reporting, the final response from Target was them stating the account was mine and they refused to remove it. I then wrote Target a letter requesting a settlement because I wanted to have this collection removed from my credit report as it is damaging my credit and they did not respond. I then called them and they agreed to a settlement of {$1000.00}, they then mailed me a settlement letter with the agreed upon amount and date. The representative told me I could go into a Target store to pay the agreed upon amount. When I received the letter ; I went into my local Target and the cashier at the service desk told me they could NOT accept the payment because I did not have an invoice. I called Target to tell them the store would not accept the payment without an invoice. She stated she would mail me an invoice, and I should still make the payment at the Target store when I received the invoice. I received the invoice on XX/XX/XXXX and I went into the Target store that same day with the invoice and the settlement letter and they again would not take the payment because I had money orders. I went to my car, called Target while I was still there and told them this store would not take my payment because I was paying via postal money orders and the payment was for a total of {$1000.00}. I had a {$900.00} money order and a money order for {$190.00} because the postal clerk had typed in the wrong amount on the money order for {$190.00} and they did not have the cash on hand to cash it for me and make the correction. I told the representative I just tried to make a {$1000.00} payment with the two postal money orders and the cashier would not take the payment so would it be ok if I would mail it and that representative told me it would be ok if I mailed however he assured me if I took the payment and the invoice and the settlement letter back into the store they should take it. I did not take it back into the store, I mailed the payment of {$1000.00}, wrote in the subject line paid in full as agreed on both money orders and waited for Target to remove the account from my credit report. 
To my horror, they updated the account to my still owing {$1600.00} which I do NOT. Target agreed to the settlement and to the terms of the money orders which they cashed immediately upon receipt. The terms of the agreement was that I pay {$1000.00} and I paid {$1000.00} plus {$1.00} and they did not honor the terms of the agreement and they did not honor the terms of endorsement of the money order which stated the account has been paid in full as agreed. I request they remove this collection from my credit report immediately. According to the FCRA they have to report accurate information, they in writing settled the account for {$1000.00} which I paid, they cashed and when they did they also agreed to the terms of endorsement which is paid in full as agreed. I am requesting this collection be deleted from my account immediately.
