Full house account that I have never had

I am continuing to get messages for a Full house account that I never had. I had dealings with ADRS who apparently were handling this for Full house. After sending my ADRS query to you, ADRS assured me that they have advised Full house that I have never had any dealings with them as indeed my cell phone number does not and should not be in their data base. That was 2024. This year it would appear a different debt collector has now taken over and is now sending me messages over this. ADRS has assured me that Full house is aware of this and yet, I am still getting messages concerning "the account that I never had".
