What I did to another company was to call them back 10 time for every call they phone me, I then told them to take me off their phone list after they answered then hug up, they stopped calling!
Another method is to put them on hold for 1/2 hour & see if they are still there after.
I have requested that this number be removed from their call list, but they still continue to call. Day or night. The caller is becoming ruder and ruder, when I ask hat I be removed from their call list. They will not give me their name. Getting very frustrated with them.
