Installment loan Managing the loan or lease Maryland

It happened around first week of - 2015. I got a call from a finance company saying they send me a check for - dollars in the mail and it got cashed. I told him I never applied any loan with you guys. He replied they send me a check without applying and they do it all the time but this is the first time it got cashed. So I told him maybe somebody did some fraud to me and asked what should I do now. I went their next day talked with them then reported to the police. next day I went there again signed the affidavit to investigate the fraud through the bank. I did my part as per they said. After that I did not hear nothing from them. Yesterday I checked my credit and now its showing up on my credit and ruining it. I went there yesterday again and asked them about the status of the case which they say is still not resolved and told me they ca n't remove it from my credit. I did not understand many things in this case. How can I be liable for something which I didnot even know of? How can they send a real check in mail without notice or without applying? How the check on my name got cashed without my signature and identification? Now I feel I got scammed and I need help.
