Netowork of CELL IS THE WORST

I Just want to say I am sick and tired of Cell C. I have complained from last week Tuesday already, 13 Oct 2015. The Cell C store in Riverside in Nelspruit told me its a phone problem and I took the phone to an iPhone store in Illanga Mall it was rebooted and all Apps updated but still the problem persisted. I have called your customer service and given the following ref number - ***. I was told the issue will be dealth with but up until now. My phone keep on losing network and shows no service or searching. I then receive sms from Cell C saying they tried contacting me but my phone was unavailable, of coz it will be unavailable because 90% of the time network has been lost and you wont be able to reach me. I want out I wont pay monthly fees for a service I am not getting. I regret the day I ever left Vodacom for Cell C. This past two weeks alone have cost me a lot of money as clients were unable to reach me.
