Here is a little update:
I called the cell company AGAIN and after getting more of a run around and more bullshit I informed the rep that I was speaking to, to transfer the call to her supervisor because she was about to have an irate customer.
Then after cussing the supervisor out and screaming for about 30 minutes they finally started doing something.
Well after a bit more cussing, and screaming at them and demanding better service my Dad's phone is now working properly!!
It is sad that it took months to get it taken care of and of course me seriously loosing my temper to get it done, but at least it is finally done!!
