This number called me twice on 05/12/17, twice on 05/15/17, and twice today (05/16/17). Caller doesn't leave a message. When I finally called back, the caller claimed to be from Suddenlink and offered to upgrade my account for free if I just "verify" myself by giving them some personal info about my account.

This number has called nine times in three days. When I called back you're put endless hold as "..all other agents are helping customers". Bad number!

I find it hard to believe that this legit sudden link trying to sell me cable since OH YEAH I ALREADY HAVE SUDDENLINK CABLE

I called the local Sudden Link store (85541) and asked about call blocking and call rejection for the many, many calls I was getting from salesman from all over the USA. Then this number (972-746-2786) started calling me 2-3-4-5 times a day. Finally when I answered it, they identified themselves as Sudden Link staff and wanted to talk to me about call blocking and call rejection. So it is Sudden Link and apparently they wanted to talk to me about the questions I asked them to address. But if you call that number,  you hear no ring then some taped lady just says "good bye"! So it appears they were responding to my call for information.

Still calling several times a day but they never leave a message.  Unfortunately my phone doesn't have call blocking:(
Maybe it is suddenlink - I called complaining about Internet and cable last week .
