Unhappy service

I have asked 2 times sent email and called that miassit be be taken off. I didn't want it the first time but it was added by someone that phone me from Cellc.

Went to a store they tell me after 3 months it will taken off only. Why must I pay for something I don't want. I loose money from this that isn't fair to a customer. I'm very unhappy. I'm upset and want to cancel everything.
