I'm sick & tired to answear my phone 10 times a day to have nobody at the end of the line, but when you call the number 1-866-733-1560 you got a survey from ma Bell...

I got a call from this number today. Answered but got only silence at the other end, and after 5-6 seconds, a hang up.

The number belongs to Bell Mobility

I get dozens of calls from this number EVERY DAY. Reported it before and it stopped for a while but keeps calling again.

Read in a post that  it is Bell and their loyalty department. Call to give them a piece of your mind 1-800-356-8992. I am going to call right now.
