I don't know this number and it is calls me 2 to 4 times a day sometimes. They don't leave any messages to let me call back or let me know what they want. I have a blocked number and shouldn't be getting this kind of calls.
This number is Verizon Wireless calling you about your bill that is past due. You claim to pay for a blocked number and you shouldn't be getting these calls, but apparently you don't pay for it on time as agreed upon in your contract. If you want the calls to stop there is a very simple and logical solution to your problem: pay your bill. You're lucky they don't cut your service off and charge you a $15 reconnection fee.
