Who called from 5135765713

I Don't Have Sprint, and they still call - it's a research group!  Told them not call again.  I'll see if it works...

Just got a call - same as reported in this thread. Asked to hold - message repeated 4 times and then disconnected. This is my land line.
What can be done to bust these buggars?

Block with *67 I think it is. If you have caller ID this option is usually available. My telco has $1 a month charge, they waived it.

Got a call from 513-576-5713 I have seen this on the caller ID before, they wanted to talk to my son and do a survey on his cell phone.  We are also on the do not call list
