When I dial a number, I can not get the keypad to come back so I can dial an extension. When I hit show keypad I get a strange looking thing. The symbol that is on the 1 key is there but the one is down around the 9 key, the 5 is around the area of the 3 and a 0 is where the * is. I have tried pulling the battery. I have no other phone so can not even get into my voice mail. Anyone have any ideas? Thanks in advance for any assistance!
