On XXXX XXXX at roughly XXXX XXXX I was contacted at work by XXXX from a company called IC Systems. She gave a total sum of {$650.00} that she claimed I owed on an Account number ; however when I asked what the debt pertained to and requested her agency to send verification of debt from original creditor she refused to comply saying all debt is digitally submitted and she did not have that information. Then countered that I could pay {$470.00} to her agency between now and Friday or they would take further action. She gave contact info as XXXX ext XXXX. As i continued to try and verify information about her collection attempts I was told to submit payment to an address in XXXX ; XXXX XXXX, Minnesota
