New contract but cannot actually use it

Sell direct which sells contracts for Telkom Mobile called me in August promoting the Huawei P10 lite special. It was the deal of the month where I get the Telkom mobile freeme 1gig and the Huawei P10 lite for R269. I accepted the deal and confirmed details. 2 weeks later I follow up, because the phone has not been delivered, I called Telkom who tell me there is no order on their side and it was probably not processed. About another 2 weeks after a courier company deliveries a phone to me, with a sim card. I follow all the instructions that are included in the box to activate the sim card. No activation takes place after a week. Sell direct than contacts me to tell me they delievered the wrong phone. They come to collect it and a week after that I get the correct delivery sent to me. Now I am in possession of the right phone but I still cannot get the sim card activated. Sell direct does not answer its ********** 500 number. Telkom clients keep telling me they will log a case or activate the sim card. None of these have happened to date. I have been calling and wating for over 2 weeks for the activation or feedback. I have been to the Telkom direct stores and the consultants promised to follow up but has not. I dont understand what is happening, I really need someone to take this issue seriously and sort it out.
