Product: Debt collection

On or about XX/XX/XXXX I received a collection letter in the mail from XXXX, XXXX ( XXXX XXXX XXXX, XXXXXXXX XXXX XXXXXXXX ) stating that they were collecting a delinquent XXXX cellular account with a balance due of {$1900.00} that was opened on XX/XX/XXXX. I advised them by telephone and correspondence ( dated XX/XX/XXXX ) that the XXXX account was not mine as I have never had XXXX service. They advised me that they would stop collection as it was an apparent identity theft issue. They advised me to contact XXXX XXXX XXXX XXXX XXXX XXXX XXXX, XXXXXXXX XXXX XXXXXXXX XXXX directly, which I did by correspondence ( dated XX/XX/XXXX ). I advised XXXX XXXX XXXX of the facts and that this account was never mine. Then on or about XX/XX/XXXX I received an alert from an identity monitoring service I have that a collection attempt was begun by XXXX XXXX XXXX and reported on my credit report. On XX/XX/XXXX, I contacted XXXX XXXX XXXX by telephone and advised them that this XXXX account was not mine and that I already told XXXX and the previous debt collection agency ( XXXX, XXXX ) that back in XX/XX/XXXX. The agent at XXXX gave me considerable information regarding this fraudulent XXXX account including the persons actual home address in XXXX, XXXX  ( which I never lived at or even heard of ) and the XXXX cell phone numbers that were assigned to this XXXX account. She advised me that she would mark her file as a fraudulent account and stop collection. Then on or about XX/XX/XXXX I received correspondence from a third collection agency, Source Receivables Management ( XXXX XXXX XXXX, XXXX XXXX XXXX, XXXX, XXXX  XXXX & XXXX XXXX XXXX XXXX XXXX XXXXXXXX ) attempting to collect this same XXXX account. I contacted them and told them it was a fraudulent account and not mine. Source Receivables has since continuously harassed me with phone calls, at least 2 or 3 times per day, every day, for the past month. I sometimes answer their call and explain to them again that this is not my account and that collection agencies just keep selling the account to another collection agency and they should stop doing that to end this inquiry once & for all. They refuse to do so and continue to call me every day. In addition, they have reported this debt on my credit report, which has severely affected my credit score. I have contacted XXXX and filed a credit report dispute with them advising them of all of the above facts. I am now reporting this as bad debt collection practices for XXXX XXXX XXXX and these credit collection agencies to do nothing and simply keep selling this account off to another collection agency for them to harass me next month. This should have been settled with XXXX XXXX XXXX and XXXX ( the first debt collector ) back in XX/XX/XXXX and disregarded and shredded as an uncollectable debt rather than just selling the account to another debt collector to start the entire harassment process over again. Furthermore, Source Receivables should be reprimanded for their debt collection practices of harassing me with multiple phone calls every day and reporting this on my credit report after they have been told on several occasions that this debt is not mine.
