No care for customers!!!!

On the 16th August I entered into a contract for a data package at the Vodacom Chatz Eastgate branch. I paid the connection fee of R106 and was advised that I’d be connected immediately which was not the case but I only discovered that at home. I was told that an amount of R98 would be debitted 2 days later as part of the service fee. On the 17th I returned to the store requesting a cancellation due to a change in my circumstances and in any event the service had not been activated, I was advised to send through a written cancellation request which I did! I have received multiple emails from the store advising that they “unfortunately” cannot cancel the contract despite customer service advising that it should be possible to cancel and advising me to return to the store and request the cancellation. I had even sent an email requesting to meet with the manager to which I have not had the decency of a response! Today they debitted R211 from my account & it’s not even the agreed debit order date. I was never told about this!!! I was told that R98 would be deducted. I’m really fed up with the terrible treatment I have received. I want this contract cancelled!
