Some calls they don't refund...which is irritating...I usually just call and I am very polite, they usually give me credit. It's not that CBS is cutting us off, it's the jail...for "head count", fights, etc. Anything the jail feels necessary to cut phones off for. The phones are crappy and disconnect on me several times...Usually, most times, I get my money back, being polite and understanding. There have been a few incidents where I haven't gotten my money back, but I just fight it, send the faxes and eventually either get it or forget it...I think the money I have lost is still worth getting to speak to my loved one...
