Disappointing customer service

Utterly disappointing and pathetic service from Telkom. I have 2 telkom contract numbers and both were up for renewal. On the 17/04/25 I went to the greenstone Telkom to upgrade my contract, the lady Sancia, processed a wrong colour device on my name. She did not have stock of the color she processed. Because it was too late to correct her mistake as it was at 18:00, she said the back office was not available to correct it. I left the store very disappointed, I waited nearly 2 hrs for nothing. I went to the festival mall Telkom on the 19/04/25 and renewed my other contract on my second number. I called Telkom last week to see if that order from greenstone was cancelled but the call centre lady was rude and put the phone down on me. I now want to cancel my contract on *** and I want to be within the right time frame to do so. I called Telkom and they said gave me a story that the greenstone order needs to be cancelled before I can cancel my contract.i called Greenstone today and spoke to a lady, Patricia, and she was suppose to call me back and she has not!!! It's been more than a month now and nothing has been done. It takes a long time to get through to Telkom and then when I do, the matter is not resolved. Telkom tells me i must contact the store and the store tellme to contact Telkom direct. The worst part is that these people from telkom both the store and call centre people are rude , they make you feel as if you are the one that did the mistake in the first place.
