No service whatsoever

They phoned me for an update on my current contract - it was with Altec auto page. I wanted to go with Cell C direct and tried to cancel the contract with Glocell, but this was to no avail. When the finally phoned me back and offered me an upgrade with a nice phone for a good price I decided to give them a chance and upgrade. They said it will take 5-7 days for delivery, after 3 weeks I phoned them and asked what happened to my upgrade and my phone. Apparently they did not have stock - no one bothered to let me know, even just an sms would have been nice. After a month I finally got my phone on Friday 3 November 2017. According to the sms it would take 24-48 hours for my micro sim to be activated. It is exactly a week now and I have to walk around with two phones as the new one works on wifi but not with data, that is still on my old phone. Phoning them does not work because you get cut off no matter which option you chose. I am so disappointed that I gave them a chance and got this! PLEASE ACTIVATE MY SIM. That is all I ask for!
