VODACOM - Disappointing , CPA where are you ?

Vodacom. I am trying to cancell my contract which has expired. surely ,legally Vodacom should not be allowed to continue deducting or demanding monthly oayments ,once the full 24 months of a contract has expired. This company insist you sign a contract , which obviously favours them. Surely VODACOM can not be allowed to put a clause in a contract that says unless you cancell in writing , even after the initial 24 month contract term has expired , then you will continue to be charged, Vodacom have in a 24 month contract , charged you for the cost of the phone , admin , vat and airtime/data. after 24 months you are charged the same amount with way less benefit to us the CONSUMER . This is ******* AND FOR THE UNEDUCATED OR ILLITERATE ,this could become costly . the only time a cell phone supplier contacts you is to upgrade a contract , by luring you in with offers of cell phones and data. WHERE IS OUR CONSUMER WATCH DOGS. WE NEED TEETH and the law makers need to protect us .Please rewrite the CPA. In the interim Vodacom ,please cancell my ****** account .*** .sending mails on line to *** and dialing *** 0r 082 111 does not help .mails are returned as incorrect address. Come on Vodacom , youre better than this . Be world class . I await a reply ....urgently or dont you talk to the public unless you need to sell to us ?
