It's Verizon Wireless. Pay your bill and they will stop calling you. The will not call you unless you owe them money. If you do not owe them money then call Verizon Wireless and clear it up. Otherwise just pay your bill.
This number called so I answered, it was Apple! They were doing a survey for the people that have purchased their product in the last 30 days. The guy said that I was the only one that answered and there was a prize for a random survey participant and I was the only one so I won a new iPAD!! I waited to post this until I got the ipad, but it is true!!
