I keep receiving letters from a collection company called Fidelity Creditor Service that I is not mine. Their mailing address is : XXXX XXXX XXXX, XXXX, CA XXXX, amount of bill is {$490.00}, account number is XXXX. 

I have asked them to provide an evidence that is bill is mine but the have not done so. I would like to assure this bill which does not belong to me, does not show on my credit report. 

Best regards, XXXX XXXX XXXX
