Terrible Service!!

<p>I just made the mistake of upgrading my contract with cell c instead of just cancelling! I took a deal for R99 month for a wifi device and data. I have not used the device or the data and somehow now have a bill for data usage when it is not a contract subsciption. I called 09 May three times before I could speak to someone whoi could actually understand something and was told a case will be opened and I will be contacted, I was not! I called twice on 16 May and was told someone will call me back. I am STILL waiting for someone WHO CAN UNDERSTAND how to assist to call me back!</p>
