Shocking Service

Have being trying to cancel my contract since October. Everytime I phone, I get "your number is on the old system, someone will call you back". No one EVER calls back. Go to the store, they can't assist, tell me I must phone after the 7th? Like where in your life? Why should I be limited as to when I can phone and cancel? Eventually got someone to assist me in November. Right, cancelled. This is after "escalating" because of the terrible service received. Now I see I'm still being charged. Phone again, the contract has not been cancelled, we will log the request for cancellation.... #$@%%... uh no! It is cancelled already! "I will get the person you dealt with to contact you"... surprise surprise, no one has contacted me... I'm shocked to say the least...
