Debt collection notices constantly received from Transworld Systems Inc . I have called twice and notified them that debt has been paid with Check # XXXX cashed by XXXX XXXX XXXX on XXXX XXXX, 2015 for the full amount of the debt of {$40.00}. ( Scanned copy with full cashing information attached ) My account # at Transworld is XXXX. However, Transworld continues to send me collection notices more than weekly despite my calls. The XXXX XXXX XXXX XXXX, XXXX XXXX XXXX XXXX, XXXX XXXX, XXXX VA XXXX goes directly to an answering service when called. I provide all requested information and am told I will be called back within 24 hours. After 5 calls, they have failed to contact me. I consider the actions of Transworld invasive and abusive and the lack of response from XXXX XXXX XXXX XXXX against reasonable business practices. Furthermore, they only have one method of contact -- phone -- - which as previously stated is an answering machine with no return phone calls despite numerous attempts by me and assurances on their part.
