A couple months ago, i received a collection letter for a medical bill. I didnt recal the visit and I sent the CA ( collection agency) a dispute and request for validation within 30 days of the notice.. I sent Certified mail. They never responded or validated. Now, a new collection is on my credit report. I put 2 and 2 together and see it's the same company, different alias. the original was Central Financial Control, on credit report, it shows Syndicated Office systems. They have the same address as well, the same account numbers. It seems they are skirting the laws of validating genuine disputes by not validating, and reporting under a DBA name.
