Complaints about Phone Numbers844-720-####

I unfortunately was scammed out of $679.99 by these guys when they claimed to be Windows Support and "fixed" my computer via access through Supremo. I didn't hear from them for a month then they wanted access to my computer again, claiming this time that Russia had hacked me. I knew something was up and looked up the real Windows support. Upon learning that I was scammed, I had the real company help me file a complaint and remove all of the services from the scam company from my computer. I also disputed my charge but unfortunately lost as too much time had passed. Now I'm getting nonstop calls that I had a subscription to them and that I owe them more money, and I've spoken with "David" and told him off, and to stop calling and that I don't owe them anything. They had promised to leave me alone after the one charge dispute, but they will not back off and are now threatening to have my door knocked down to collect payments. They are liars and harassers, and it's getting to the point where I want to change my phone number. I have blocked them, but since I have T Mobile they are still allowed to leave me voicemails. I'm angry and don't know what to do anymore, but I've had enough.

Pretending to be Microsoft Support

Received a call from this company today (luxford and Truman services), they were professional and courteous. It is legitimate. They had the wrong number for the individual that they were attempting to contact. And will be removing my number. They did not ask me for my social security number or my birthdate.
