I received a phone call today from XXXX and XXXX claiming that if I did not pay {$900.00} within an hour that papers would be served. I contacted the original creditor, XXXX Bank who provided me with information on where the account was sold. This account was sold to XXXX XXXX XXXX who then sold it to XXXX XXXX who then sold it to XXXX for {$240.00} who then sold it to XXXX XXXX for {$240.00} who sold it to XXXX XXXX on XXXX/XXXX/2015 which was yesterday. XXXX claimed to have sold it to Western Portfolio Assets the same day. Western Portfolio Assets claimed their sister office, XXXX XXXX XXXX has the account. When I spoke to them and asked for a validation document from the original creditor they stated they do not have to since they now own the debt. 
How does the said debt go from {$240.00} to {$900.00}? This company who according to the Chain of Title just received ownership of the debt yesterday and has claimed to sent letters to my address over 30 days ago. I have never received a letter from this company or any company regarding this debt. They are threatening to take me to court if I do not pay the {$900.00} or an agreed upon amount within the hour. This debt is not on any XXXX of my credit reports.
