Terrible Telkom!

I have had a new Hauwei p smart phone for 5 weeks. It is the same phone number but I have a new contract (2 yr). I have gone into a Telkom store, and phoned many times, yet my new simcard has not yet been activated. I have had promises made by Telkom's representatives, and even had an email sent to the activations department (about 2 weeks ago). I received a call from Telkom and the lady promised to have my simcard activated but then spent 10 minutes trying to sell me more data (10GB for R99). She interrupted me many times and was very forceful and a bit argumentative. When I asked her to call me back the next day, she simply hung up on me. The next morning I received a call from the same number and within a few seconds of the call, she hung up on me. I am furious that Telkom has promised many times to activate my new sim so that I can use my new phone. My old sim doesn;t work in the new phone as it is too big. I am completely reliant on Telkom doing what they promised. I am also furious that Telkom is repeatedy calling me in order to try to hard-sell me Telkom's products (the above-mentioned call was the second by that same department trying to sell me more data) yet they won't provide the basic services that I I am paying for. I have logged a complaint with Telkom a 6 days ago and received an automated reply that Telkom would respond in 2 working days. As yet, I have still heard nothing back from them.
