Telkom service disappoints

I have a data bundle as part of my home package. For the past 3 months I have been trying to sort out the connectivity. The signal is available but I can’t connect. I called and was told that I have to go to the store. I went to the store, they said I need a sim swop, but I didn’t have my ID,....so I went back on another day to be told that the sim is fine and no sim swop is required but I need APN settings. And that they will send to sim. That never happened. I tried to self solve for apn and the configurations has the settings but I cannot connect. If so many technical people are not able to assist me, what must I do?!?

I called the call centre 3 times today, and while talking to an agent, I get routed to voicemail.

Can anyone at Telkom help me with this please?
