BAD CUSTOMER SERVICE FROM SHOPS AND CALL CENTRE

So on the 11 June 2019, we went to a telkom shop in N1 city and we requested for a upgrade on our adsl uncapped wifi account from 4mbs to 10mbs. When we got home later that day there was a constant red light on the router where the internet light should be. Then we phoned and we were told it was a authentication problem. Then when we phoned again we were told that they are busy with maintenance that will occur from the saturday 11 june to the monday 13 june. After monday there was no change, we kept on phoning and phoning and then eventually they tried to reset our password and reconfigure our router but every time when we get to step six then the red light comes back on and it says the connection failed. We tried to take the router in to a telkom shop and then they tried to reset the password and then their system was offline. The technician took our details and said he will sort it out on his side when the system is back on. We contacted him via email and still the system was offline. Then it was again the same route phoning and phoning and phoning and everyone keeps on doing the same thing trying to reset the password but yet it does not work. The past weekend we went back to a telkom shop and still nothing could've ben done because the system was offline, but the customer before us in the line was helped with a password. So today 19 June 2019 we went back to the telkom shop at century city after we were advised by a technician to take the router back and let them test it on their cables and if it does not work tale one of their routers and use our details to determine if the router is faulty, so when we came to the shop once again with our luck the system is offline and all the technician can say is sorry but the system is off. He didn't even want to try one of their routers with our details as we were advised to do he just said it wont work without even trying. I did get upset and said a few not do nice words and then the technician just ignored me the whole time and he neglected us as his customers he kept on helping other customer while he knew we were not done yet. So its not just one telkom shop or one telkom technical support person at the call centre that is not helpful, its ALL OF THEM !!!! No one knows what good customer service is or know the correct protocols to handle their cases . I wish someone can do something about this .
