I can only think of four things that might be going wrong-either you weren't signed up with your service provider for call-blocking but assumed you were and followed the procedure to block but it didn't work; you are signed up but didn't follow the procedure correctly; the caller changed their number or you didn't block them but you thought you did.Contact your service provider and have them sign you up or walk you through it, or look in your owner's manual for instructions.If you were signing up for Google Voice, getting it set up can be confusing. In this case, the setup instructions are available on Google. If you need further assistance, get someone to help you.

Called twice again, once at 11:31 MST and another at 16:32 MST.

no vm left.

Have been calling me repeatedly, daily. I'm glad I found this website!They called today and asked me if they could talk to (my name) and I said I was speaking and then they hung up on me...So I blocked the number

They keep calling for no valid reason.   I wish they'd call themselves!!

...this last call was Dec 8th 2011 just after 1:00 PM

Yup.  Just got a call from them too on my cell.  I actually picked it up, but they hung up immediately afterwards.
