No Cellphone reception

This is the 5th time im complaining about this. I was on hold being transferred to different departments from 14:00 till 16:15. I want my cellphone contract cancelled. I spoke to several managers which all said the same thing that it's clear there is nothing cell c can do to fix my service issue. I am now completely sick of this!!!!! I have been told they would phone back to give me a number i can use to go and stop my contract at the store. I am still waiting for this networks department. How many times must i complain??? And now im paying for a contract with no service. Tried all your solutions roaming on Vodacom etc.. IT DOESN'T WORK !!!!!!! I WANT SOMEONE TO PHONE ME GIVE ME THAT NUMBER SO I CAN RETURN THE PHONE AND CANCEL THIS CONTRACT. IF NO ONE CAN DO THIS THEN I WILL BE FILLING COMPLAINTS AT WASPA !
