Unprofessional, heartless dont care attitude of Vodacom

I been a customer of vodacom for more than 20 years. My recent experience with them is not only disappointing but leaving much to desire. Last year during August, they called me proposing to upgrade my current contracts which I declined. Instead I requested a new sim card with a portable router that I intended to use as additional line. Instead of sending me a portable router, they send me a fixed router which I could not carry around as intended. I raised an objection to this and they immediately send courier to come and pick it up with the sim card and promised to cancel this new account. During my next month payment statement, I noted that I had been debited despite that they assured me that it will be cancelled. I called and lodged a complaint and was promised that the transaction will be cancelled and be refunded. However, this did not happen. At the beginning of this year and last week on Thursday, I again complained about this deduction which continued despite that I have been promised that it will be cancelled. I was told last week that definitely it is going to be cancelled and will receive an SMS in that regard, but nothing has happened until now. Secondly, I have also requested last week on Thursday that my one other month-to -month account be cancelled. Although I was also promised that this will occur within 24 hours thereafter and will receive sms in that regard, that has not happened yet, leaving me to the conclusion that deduction will also continue unabbated like the above account which until to date has not been cancelled.This is the sms I received from them "You will receive an SMS and Email with your exact cancellation or conversion date. Until such time, your Vodacom Contract Cancellation is not confirmed" I have lost hope in dealing with vodacom as it is clear that they dont care about my complaints. I am even contemplating cancelling all my other month to month contracts going forward.
