calling a Magic Jack # that I never use, but exists through the app on my phone... I have most  ignored it but now I see that they've called about 20 times since the beginning of this month...

Has called once a day for at least three weeks, always between 5-7pm.  My Robocall service cancels out the call after the first ring.  Caller ID identifies caller as "Controlled Network".

Called them back, said it was AT&T, advised it was a work phone, he apologized and offered to put it on their do not call list before I could even ask.

ATT call appears as Controlled Network. Calls for more than 2 month at least twice a day. No message left. Unwanted.

call appears as Controlled Network. Calls everyday twice a day. When i answer, they hang up. When i dont answer, they never leave a message. Unwanted.
