A company called " XXXX '' attempted to take {$200.00} out of my checking account. In addition they attempted to take {$25.00}. These attempts were made simultaneously. Two weeks later I started receiving calls from XXXX XXXX XXXX XXXX at my job and the caller claimed that they were attempting to collect a debt. I immediately asked for the details in writing and they stated that they had sent a letter. They had not. Each time they called I requested the details in writing. They claimed they sent it. I never received it. I stated, " if that is the case, FAX me a copy of the one you sent. '' They refused. I told them if they could not send it in writing, that I did not believe they were a collection agency but a scam. I asked them to stop calling me. They continued to call me every day for weeks. On XXXX/XXXX/15, nearly two months later, I received a letter from XXXX XXXX XXXX, a unregistered collection agency claiming I owed a company called CrossCheck, Inc. the {$200.00}. I have never done business with CrossCheck, Inc. XXXX Louisiana Revised XXXX XXXX requires collection agencies to be registered. ) I have sent them a dispute letter since receiving their letter. ( I can prove the calls via cell phone records. )
