Please Block

I am getting calls from this number several times a day. When I answer there is no one there!! Sounds like a computer connecting you for a telemarketing call but then you are disconnected!! VERY ANNOYING!! Tried to call the number to ask to be removed from the list and was on hold for a representative for 10 mins. then disconnected!!!!! Please stop these calls!!!

They keep calling and asking for Heather.

This company calls several times a day.  Since I don't know who they are, I don't pick up the phone.  They never leave a message.

I've been getting numerous phone calls from these people called Future Vision. They calling my phone everyday and it's getting very annoying. Is there anyway I can block them from calling me?
