CANCELLATION NIGHTMARE - Pitiful Non Service

Literally at my wits end and hate to use social media and to go the Hello Peter route, but honestly I'm at a loss at what to do. I've been trying to cancel 2 conracts with Vodacom for two years. I have so many reference numbers, I've lost count. I'm not even sure these are reference numbers anymore or just randomly generated numbers to shut the client up. I need this issue resolved. There is no feedback from Vodacom, e-mails get read with relevant queries and automated responses received. On two separate occasions I've received written confirmation from Vodacom that my two lines are cancelled. All necessary documention has been forwarded on more than one occasion, yet there is no accountability from Vodacom side for this horrific display of non service.or lack of interest. It's shocking to say the least. I will be taking this further from a legal perspecive and Vodacom have had more that ample oppurtunies to respond. I shall also be filing for costs to be for their account. I have all mails from Vodacom stating that these lines are logged on the system to automatically stop at the end of their 24 month period, yet still I'm being charged. SORT YOUR SYSTEMS OUT AND REVERT BACK TO CLIENTS! We the one paying your salaries! Numbers in question which need immediate cancellation and IMMEDIATE refund: ********** 190 and ********** 120.
