No Cellphone reception

This is my fourth time I am complaining. If i do not receive i proper solution this time i will be lodging a complaint at Waspa. I don't get service i am paying for a contract that i can't use. I want this contract cancelled i am completely disgusted in your customer service and overall cellphone service. I have been complaining for months, dropped calls no service i am sick of this. Changing my roaming to Vodacom doesn't work. We have another cellphone here on cell c with the same problem switched contracts to Vodacom no problems. I want this contract cancelled or i will be complaining at WaspaMassive specials at Agri Liquor Store only in George. Specials until Monday. To avoid disappointment come before stock runs out
