BAD SERVICE- VODACOM

Bad Service- Good Day , I would like to express my dissatisfaction & disappointment regarding the service received from Vodacom. I have a data bundle contract with Vodacom which expired in May 20. I was not contacted for a renewal and my account was put on to a month to month contract. Non the less my account was debited on a monthly basis with the premium being increased as the contract had expired and the "higher amount"was reinstated. My account was debited on a monthly basis and paid in full even during "the global pandemic: whilst everyone was going through difficult financial crisis. In Jan 21 I realised that my monthly instalment had increased and went into the Musgrave Centre store to enquire the increase, on my enquiry the consultant advised of the monthly contract and the price increase which I did not agree to and he therefore assisted me in cancelling my contract and verified the same. MY account was on a nil balance on cancellation. I have been debited again in Feb 21 & Mar 21 whereby I had reversed the payments due to feasibility. I received a statement for April now owing +-R800, I called the cancellations department to enquire why I am still being billed when I cancelled in Jan21 only to be pushed from 1 department to the next, cancellations have now advised that the cancellation was not done in Jan 21 by the consultant of the store and that I need to pay the arrears to have my account cancelled. This is ridiculous as firstly I have not been using the data since last year due to water damage on the device and sim, I cancelled my contract in Jan 21 when my account was on a nil balance, and due to the negligence of the consultant not cancelling my contract which I never agree to be renewed in the first place, I am requested to pay a further R800 to have my account cancelled. I hereby request for this matter to be escalated and resolved urgently. Please note I am disputing the balance outstanding and request for it to be reversed and my contract terminated with immediate effect.
