Product: Debt collection

I had stated in my complaint against Blitt and Gaines that I had been communicating with XXXX XXXX through certified mail and am insisting on written communications so a record of what is said exists. I asked Blitt and Gaines to provide validation of debt and to verify the birth date and last XXXX of a Social Security XXXX of the person who signed the original loan contract. I used CFPB so I had a resource on which to rely in the possibility of a future event in which other debt XXXX start to harass me again over the same issue. I do not want to spend more time and money on certified mail and I definitely don't want to speak with them over the phone where I have no record of what is said. As discussed in my complaint, Blitt and Gaines is not the first company to attempt to collect this debt and I have requested they verify a birth date and the last four of a Social Security Number before they proceed with any other action. Either XXXX or XXXX XXXX  should have a copy of the original loan contract. When loans are taken out, both of those identifying factors are verified. This should have been verified by XXXX. I can verify my birth date and last four if my Social Security Number as soon as they verify that information from their records. This would also determine if the fraud department even needs to get involved at all. 
XXXXI was contacted by Blitt and Gaines , P.C . on XX/XX/XXXX trying to collect a debt for {$2200.00} for XXXX XXXX XXXX, XXXX with a reference # of XXXX. XXXX XXXX XXXX has already tried to collect this debt through XXXX XXXX. I had contacted them to tell them that it was not my debt and asked them for validation of debt and then asked for them to verify Social Security Number and birth date of the borrower. Their response was not to respond to me and hand the debt to you. I started to send off communication via certified mail but was getting very frustrated with having to repeat the process I just went through with XXXX XXXX. I did write a letter and am sending this through the CFPB. The first paragraph is the complaint I filed against XXXX. The second paragraph is the letter I wrote to dispute your effort to collect a debt that I have already disputed. 
XXXX was contacted by XXXX XXXX ( XXXX XXXX XXXX, XXXX, SC XXXX ) ( XXXX ) with a letter dated XX/XX/XXXX saying that they were trying to collect a debt for {$2200.00} reference # XXXX for XXXX XXXX XXXX, XXXX, listing them as the current creditor and providing a reference # of XXXX. The original creditor was listed as XXXX XXXX  with a original account # ending in XXXX. I have never heard of nor from either of these two businesses. I contacted them through certified mail requesting validation of debt and stating that had never dealt with either company and did not owe this money. It was received on XX/XX/XXXX. I received communication from them dated XX/XX/XXXX providing me with a bill of sale for the naming XXXX XXXX XXXX XXXX as [ initial seller ] [ servicer ] on behalf of XXXX XXXX, XXXX XXXX and XXXX XXXX XXXX as the buyer of the loan XXXX  was trying to collect. It also provided me with a delinquent payment schedule with monthly payment amount of {$130.00} that I have never made from any of my bank accounts. I wrote back, sending that communication via certified mail which was received on XX/XX/XXXX stating that the debt that they were trying to collect was not mine. I also requested them to verify the Social Security XXXX and the birth date of the person who signed the contract and asked for the signature as well. I never heard back from XXXX XXXX. I just found out that their reaction to this request was to sell that debt to another debt collector, Blitt and Gaines , P.C . who is now trying to collect the debt from me. I've conducted all of my communication through certified mail and it is getting both expensive and frustrating. I would like to not be contacted for this debt again. It is not my debt. I can prove it with bank records, but easier than this, they could have ruled out my involvement in this debt with the verification of the Social Security number and or the birth date from the original loan application, however, failed to do so. 
XXXX I am disputing the debt you are trying to collect for XXXX XXXX XXXX with a reference number of XXXX, which was listed with a reference number of XXXX at XXXX XXXX. This is not my debt and like XXXX XXXX, you have contacted the wrong person. I disputed the debt back in XXXX of XXXX, asking for validation of debt. I was given a delinquent payment schedule that does not reflect any of my financial activity between XX/XX/XXXX through XX/XX/XXXX. I have never dealt with XXXX XXXX XXXX nor XXXX XXXX. I have never made monthly payments of {$130.00} to anyone and have no clue what purchase created the balance of {$2200.00} that you are trying to collect. I disputed the debt and asked them to verify my birthday and the last four of my Social Security number. I am assuming that their reaction was to sell the debt to you. I am not the person for whom you are looking. I am asking you for validation of debt, for a copy of the original credit application, and for you to verify my birthday and Social Security number. This is not my debt and would like to not be harassed in the future over this matter by more debt collectors.
