The best thing to do is save the number into your contact's. Then on the newer cell phones you can block that number...I have 43 numbers on my cell that are blocked now. LOL
Just got a call on my cell saying from Cambridge. They left no message. It is so annoying. I hope they suffer from people calling them all the %#*€ing time!
it called me today and was silent when i answered. I called back and a recording said, "your account balance is insufficient to call this location" i called it from another number and got the same message.
