Disgusting Service - Still no contact after being told a Supervisor will make contact.

I am due for an Upgrade so I decided to order it Online as I have heard it is easier in todays AGE however I have found this experience NOT TO BE THE CASE! I Successfully upgraded online where I was sent an email to say it was approved and that I must wait to be contacted from the Delivery Department from MTN SHOP ONLINE. I got this email on Friday the 3rd MAY 2019 and read that I will be contacted within 3 - 10 WORKING DAYS AS THIS IS MTN POLICY. I have to date phoned numerous of times to customer care and kept being put through to MTN DIRECT which don't deal with MTN SHOP ONLINE, and I have also emailed MTN SHOP ONLINE AND I have still not been contacted. I have however received the SMS's saying I am on my new contact. After complaining on Hello Peter, I was then advised that I will be contacted by an Mtn Supervisor and still to date I have not been contacted. I then went back to MTN shop last week Monday 27th May 2019 as I was told I must now get an Affidavit from the Police Station to say I want to cancel my upgrade from the MTN online shop and this will take 5 days approximately for them to cancel it on their side then once this has been approved they will contact me so I can get then my phone directly from the store. I went to the Cascades MTN Shop, Pietermaritzburg, KZN - yesterday 3rd June 2019, only to be told that now it takes 7 - 14 working days!!!!!!!! Why must I now wait for a cancellation when I have been waiting since 3rd MAY 2019 to even be contacted??????????????? Mtn like to waste your time and make promises which they dont stick to!!!!!! Absolutely disgusting service. PLUS I Have been charged Two months for this NEW PHONE I HAVE NOT YET RECEIVED. THANK YOU MTN!!!!!!!! in todays age you would expect things to get done a lot quicker, but this is certainly not the case with MTN.
