Shady people... Never settle anything with them unless you have it in writing.
Agreed to settle for 33% of balance but I asked them to send in writing before I made a payment. First refused, then manager said, would send the offer letter. I did not receive anything for a month. Called today and 1st person I spoke to said, they sent letter on 6/11/2020 but had to transfer me to someone else. That second person said, they did not send anything and our last contact was in April 2019 not in June 2020 and they would not make that law offer (on account that is 4 years in collection). I am happy I did not make payment in June and requested in writing because like now they denied our conversation they would do the same and after taking 33% they would keep collecting the balance. I am not planning any big purchases next . half years, so not making any offers any more, I will wait till it fells off my credit.
