BAD SERVICE

i have never signed up with the worst cell company ever. First the tried to rob me by over billing me and then correcting it wrong still. The extras that were offered never came and then i finally cancelled and the still took my EFT out my bank with out returning the 1 month advance payment as I was told. i will be going to the authorized people that deal with this, they also told me is was though another company doing the sale but using their name, what a joke
