I was billed {$270.00} by XXXX XXXX XXXX which I paid by my check No XXXX dated XXXX XXXX, 2015. My check cleared my bank account on XXXX XXXX, 2015. I subsequently received a debt collection notice dated XXXX XXXX, 2015 from Transworld Systems Inc., Collection Agency, XXXX XXXX XXXX, XXXX, PA XXXX, correspondence to be sent to XXXX, DE. I have since received further collection notices dated XXXX XXXX, 2015 and XXXX XXXX, 2015, despite the fact I advised the collection agency on XXXX XXXX, 2015 that I dispute the debt because it has been paid.
