Telkom - *********** & horrible customer services

So, I requested a cancellation on one of my many contracts on 31/08/2020 & received 2 emails confirming the scheduled cancellation on the specific number indicated by me. The cancellation was a contract for a mobile phone that had expired. A month later I find that my mobile data modem had stopped working. I call Telkom and they say the line is active. After a number of attempts to fix the problem, the consultant says the line was cancelled. So then I ask how come because this was not the number that I had cancelled and I had email proof from telkom. I could get no answer. I asked the consultant to reconnect the data line and cancel the correct number, but she said this was not possible & that I would now have to re-apply for an new data contract. This is @#$@/$!!! ridiculous! They cancelled the wrong number and I must now apply for a new contract. Besides, I had just topped up with 20 gigs of data b4 the month end at about R350.... now all was gone. Another thing is that I still got billed full and in advance despite their cancellation. I wad then told that the department that could assist will only be able to on Monday. I asked for a number for someone in management and was told no one was available and that someone will call me back. Now I have to sit for the whole weekend without a service that I have paid for. What a schlep!!! Telkom provides poor service and horrible customer services. A typical example of state-owned institutions with poor service delivery. I am going back to Vodacom. For those contemplating Telkom.... be warned... think again.
