Poor Service

I am so frustrated... no-one is able to assist me at all and I CANNOT find a landline number to phone for any of the offices. I cannot get through from a landline and I CANNOT use my cellphone so basically I am stuck!! I happened to get a call from the upgrade department who when I told her I needed to phone and landline she said can only use my cellphone and then promptly put the phone down on me!!!! What do you do if you cannot use your cellphone???? I then tried to to ask them to call me back... well after going around and around in cirlces you just keep coming back to the help topics.. so basically my only option is to go into a store which I already did.. they could not help and reported a service call... I then waited the 2 days to get a response which I have received and it does NOT RESOLVE MY PROBLEM.... as they instructions they give does not compute with my cellphone settings!!!!!
