Has anyone had any luck with the "customer retention"?

I called and talked to nice guy, but he really didn't answer my question.  I am looking at getting a new phone, but since I moved to my current location, I've had horrible reception, one or two bar mostly.  I was wondering if there was anything they may do to keep me with Verizon, instead he takes me through cleaning out memory, resetting the network, and ends with I should get a new SIM card.  About a month after I moved, I bought a new phone, thinking this would help but nothing changed. I sucked it up, and eventually, I got a land line.
