*****ulent contract upgrade and pathetic customer service support

My contract was upgraded without my approval by a Vodacom consultant. I have requested evidence of this upgraded such written communication or recorded calls to prove that I initiated this upgrade which Vodacom has failed to provide, they instead said that it was an error on their side and will have this contract cancelled. The cancellation has not been actioned to date instead they send me monthly statements that my account is in arrears as I have blocked all Vodacom debit orders with my bank. I have been dealing with Customer Service Team leaders/ Managers who have also failed to rectify this issue Yasiem and Bhekokwakhe. If only Vodacom was as efficient and professional as on-boarding new clients when servicing existing clients then I would have such a problem. This matter is affecting my credit profile and I refuse to pay for a service I don’t use. Vodacom will you urgently attending to my issue!!!
