Product: Debt collection

The company : XXXX XXXX XXXX On XXXX I was made aware that XXXX XXXX XXXX had purchased some credit card debt in my name from XXXX XXXX, Indigo Card, while it was under dispute. 
I called XXXX XXXX XXXX that day XXXX and put the account in dispute and told them I feel the payment amount is unjust. I was in the XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX and I only used the card a couple of times before being hospitalized, so there was no way all of the debt, plus late fees, plus interest were mine because the card had been maxed out, which I suspect was my girlfriend at the time. About 15 days later they sent me an email of a bill from the credit card company and that was it. So on XX/XX/2021 I called them back and redisputed the item with them and explained my situation again. Well, on that day I asked the person I was talking to if they would please just offer me a fair settlement and an allotted amount of time to pay before they put it on my credit report. Within about 10 minutes he came back on the phone and told me the lowest they could do was {$450.00} and give me 90 days to pay it. After that 90 days, they said it would go on my credit report if it wasn't paid in full. Even though I still felt like it was very unfair to me, I accepted and asked them to mail me a letter with the terms we agreed on and that was it. Skip to XXXX, 15 days later, I checked my credit report and the account had been reported. So again, I called spring oaks and the guy who answered Said he seen in the computer where we set up the deal and agreement and said he would transfer me to a supervisor. 
So a guy, I do have a name but will not mention at this moment, got I not the phone claiming to be a supervisor and told me that the dispute was resolved and they were allowed to report it... 
I told him it wasn't resolved at all, that it hadn't been 90 days and plus they agreed not to report it until after the 90 day period if I hadn't paid, which I would've... 
Well after that he told me that my only option now is to, I quote : " pay the {$450.00} today and he would make sure it would be removed from my credit. So he was leveraging this against me to make me pay money I didn't have at the moment. 
I told him I just didn't have {$450.00} right now and he belittled me and told me that {$450.00} wasn't much money to go get it and call them back and pay and he would remove it. I again said, I don't have the funds at the moment and this wasn't our agreement and now this report has dropped my credit score like 50 points, then he told me the sooner I could pay the sooner he would make sure it stopped affecting my credit. Well, at that point I told him I was contacting the FTC and CFPB him and he said, " we hear these threats daily, this doesn't affect us ''. 

Well, later that night I called XXXX  to tell them what was going on and they said the account had been removed. She said there was no company on my credit report with that name. So, after all of that they did remove it that same day because they knew they were wrong for threatening me and stuff. 
At this point I really don't ever want to deal with them again I think they should dissolve the amount they say I owe ( I dont ) and leave me alone, because honestly, XXXX is the original amount and they offered me a {$450.00} settlement. I feel like after being treated the way I was that they violated enough FCRA laws to be fined and perhaps owe me well over {$450.00} or {$620.00}. All I can say is I do have the man 's name that basically leveraged my credit score against me to make me pay them money I couldn't get. And a screenshot of the account being on my report, and my phone log of the phone call to them, and proof it was removed that evening after the call to cover their tracks. I'm not sure what my options are, but hopefully there is something after the onslaught of verbal abuse, trying to use my credit report against me, and reporting an account that isn't accurate and still in dispute. ( Was in dispute before the report ).
