Debt collection — National Credit Systems,Inc. (OH)

Debt was paid. National Credit Systems advised that I owed a XXXX security deposit to XXXX XXXX XXXX stating that XXXX at XXXX filed a security deposit claim. I received a copy of the ledger from XXXX at XXXX showing that the XXXX deposit was returned to XXXX XXXX XXXX by XXXX at XXXX and submitted the receipt to XXXX XXXX XXXX and National Credit Systems. I was advised that they National Credit Systems not remove the amount until XXXX XXXX XXXX responded to the dispute and XXXX XXXX XXXX advised they have no access to any information on the account because National Credit Systems is covering the account.National Credit Systems has hung up on me several times ; refused phone calls and yells when I get someone on the phone. I would ask that that the XXXX amount is removed from my credit rep
