Bad service and attitude

My account is used by my mom. We filled out forms in 2 branches and they still have to talk to me before they talk to her! The second is the attitude regarding signal related problems basically they don't care and the third when they phoned they said that they wanted to upgrade the contract, while my mom was talking they cut her off mid sentence because she asked them why we should renew with all the problems we get and put her through to the automatic rate my service division!!! How can they advertise how good they are when their service is atrocious!!! If anyone responds to this, which I doubt, they will also talk to my mom because I am with a professional cell company!!
