Who called from 6104593989

I received numerous calls from this number no message. Tried to call the number back and a fax picks up

This is from the George W Hill correctional facility in Delaware County, Pennsylvania.

Just got a call from this one-it gave the correcional facility too, that I was supposed to press one for English, 2 for Spanish, etc.  I hung up.

This call is from a prison and is sometimes used for the inmate to make a free call to you from the prison at no charge to you (It will announce at the beginning of the call if its free to you) it is OK to press 1 or 2 for your choice of languages. It should also announce who's trying to make the call.

Why I have to pay?to talk to my dad?
