Having a problem with iphone 4S. Phone calls are getting dropped and cutting in and out.

[gvenn]

I seem to have very little or no service at all recently.

All my calls are cutting in and out or hanging up in the middle of a conversation. I have to stand in the corner or my kitchen to get a clear call or get at least 2 bars.

I called Verizon yesterday and tried a few things they suggested but nothing worked.

I dont have another phone to call them back on since they suggest we call from a different phone until the late evening. Someone was supposed to call my back and never did.

Not sure on what else to do.

I am extremely frustrated and annoyed that I cant even really use my phone.

HELP
