Customer service at Telkom stinks as usual

Once again I get to experience the worse customer service from Telkom. I upgraded once again and my bad experiences with Telkom came back to. To make a long story short, I upgraded more than 2 weeks ago through Sell direct on behalf of Telkom. I received the call that my upgrade is due Monday 12 Oct. 2020. The afternoon of 14 Oct I had the phone in my hand delivered. I specifically mentioned that I don't want a black phone. The consultant reassured me that I will get the colour I requested. When I opened the box it was a black phone. To make matters worse they immediately disconnected my sim card without calling to ask if I'm happy with the phone. I spent the afternoon trying to call Telkom but I did not have network. I had to buy airtime to my son's phone to phone Telkom only to discover that I must deal with Sell direct as they delivered the phone. It took Sell direct two weeks to get back to me. (I'm not going to go into how many calls I made to Sell direct and Telkom and the managers are never available to speak to me and I left messages and not the manager of Sell direct or Telkom bothered to call me back). Finally the consultant from Sell direct who initially called me about the upgrade and promised me the colour phone I wanted, called me Tuesday 27 Oct to acknowledge her mistake but unfortunately they don't have stock of the colour I wanted. Up to today no one from Telkom called me about the messages and complaints. This is not the first time this happened to me. A few years ago I upgraded in store at KC branch and Telkom gave my number away to another user. I was with a brand new phone without a number for a few days before they could resolve it. I just can't win with Telkom whether I go into the store or online upgrade. They left me with no choice but to cancel my contract.
