*** cancellation

I had a contract with Vodacom cell number *** . When the contract was due for cancellation I called the hotline and requested for the contract to be cancelled . The consultant failed to advise me nor notify me that the contract still had one month to run. All she did was load a cancelation and converted the line to pre-paid . I have send Vodacom numerus emails and till today this issue has not been resolved . As per there policy all calls are recorded and I've asked them to listen to the call recording with no response . Today I have been blacklisted by them for there error and I'm still struggling to have this matter resolved . I have been struggling from 2017 and still nothing . Is this the way your treat your customers
