No feedback, no answer at the call centre, no phone

Good Morning, I received a calls again from Selldirect between the 8-10 January I had to do the whole upgrade process again. They were reassuring me that I will receive my phone on the 17th January. The morning before and I've been calling for a follow-up but no answer. So during the course of the day they try to contact me however im in one of our offices at work where we are not allowed any cellphones, cameras or recording devices, my phone was locked outside the office. So i missed the call, when i exited i then tried calling them and guess what no answer as usual. So today i get a call saying the want to upgrade me. I mean WOW this company has serious traceability issues. Guess what they did they removed my ****** application and asked me to start this process again!!! Like WTH are you serious!!! I have to wait another 7 days??? Ive been waiting since the 12th of December 2017 how long are these 7days!! Service is pathetic! Id rather cancel, Selldirect is the worst call centre ive ever dealt with and Telkom will be losing lots of money with them.
