We owed {$320.00} to original company ( XXXX ). After a phone call from them regarding payment, I advised them I never got a bill. I gave them my current address in XXXX. It took three phone calls for THEM to get it correct. By that time they put the debt into collection ( Transworld Systems , Inc. ) I paid the bill on XXXX XXXX, 2015 after finally getting an invoice from XXXX. On XXXX XXXX, 2015 received a call from debt collector ( Transworld Systems XXXX. I advised them that this account had been paid on XXXX XXXX. Transworld said they did not get payment info from XXXX and needed it. So I called XXXX and was told they would send payment info to Transworld. In XXXX, 2015 received call from Transworld again and also XXXX XXXX. I called XXXX and spoke with XXXX and advised of the harrassment from Transworld. She called XXXX and they denied calling me. Today ( XXXX XXXX, 2015 ), I received ANOTHER notice of collection from Transworld Systems , Inc . I again called XXXX and spoke with XXXX regarding notice from Transworld. He advised that my account was paid and he did n't understand why Transworld was sending me a notice. He advised that he would send this complaint to his supervisor and have him/her call Transworld tomorrow ( XXXX/XXXX/15 ). I did advised him that I would be filing a complaint as not only was Transworld Systems Inc. harassing me but XXXX was also at fault for not making proper corrections to my address so I would get the invoice and be able to pay it in a timely manner thus avoiding collections. Address for Transworld Systems , Inc. is : XXXX XXXX XXXX, XXXX XXXX, XXXX, XXXX XXXX. Telephone # XXXX. Address for XXXX is : XXXX XXXX XXXX, XXXX, XXXX XXXX. Phone # is:XXXX. I hope someone can do something about this company ( Transworld Systems , Inc ) harassing me. This has been more frustrating than recovering from XXXX.
