They call every few weeks. No problem their number is blocked and my phone doesn't ring. Then I call and report them to the National Do Not Call registry. Hope they are investigated and fined.
Got a call from them and answered since I am from Michigan, a call from 734 is not unwarranted. The guy called me by name and referenced the car I have. Told him I wanted to know his company name and phone number. Gave me the name as "vehicle protection direct" and number as 202-204-2992.
I've been called by these people several times. I answered the first time and told them to remove me from their list of numbers. I was told it took 24-48 hours to do so. A year later, I'm still getting about 1 call every other month.
