We were charged over {$100.00} by XXXX XXXX XXXX for some unknown reason and when we called the customer care to find out what it was about, they did not give us any proper response and they said it was some technical error from their side. After 4 months we get a call from Enhanced Recovery stating that they are coming to collect the bill amount and although we did not know what it was for, we paid duly. Its been over a year and now we notice that they had filed a delinquency report against us. Our credit score has been hit by XXXX points and there is no one coming forward to help us with it. We did not notice this statement until recently when we went to the bank to get a loan to purchase a house. We have proof that we have paid the company, can they still hold this against us?
