STUCK IN EV WILL NOT RECEIVE CALLS!!

Recently upgraded to 6.1 and no problems except for one.

My phone shows EV constantly. I can not receive calls at all. As soon as I try to place a call, EV switches to 1X and i lose signal for about a second and then it comes back and places the call?????

As soon as I disconnect my call, the phone goes back to EV mode and I am unabable at that point to recieve calls at all.

I should add that I do not recieve text messages or voice mails until I try to place a call and the phone switches back to 1X.

I spent 1 hour on the phone with Verizon and they tried to give me a new A-key and did not work. They also looked at a couple of other settings only to tell me that they had to escalate the problem to a different department and they should be calling me back within 5 days. (((HOW WILL THEY CALL ME BACK)) Hopefully my land line number.

i have tried everything and read through forums and have not found any answers.

SOMEONE PLEASE HELP
