I just got a call from this number, it was a Verizon courtesy call regarding my recent upgrade to a Blackberry. Just asked if I was happy with it, and if I was told about such and such function and so forth.
Verizon trying to get you back as a customer. Did you recently cancel an account with them? They're pulling the same stunt on me. Don't answer your phone, they'll go away eventually. Annoying though.
They just called my ATT cell number, only they left a message. Was for someone else and left a call back number 800-523-8573. Lady was actually pleasant and said she'd remove the number from the call list.
