Vodacom has STILL not addressed the credit limit issue

I tried to upgrade to the new Samsung Galaxy S10+ at my local Vodashop, they helped me transfer my account and placed the order for the new device. When I returned to the store to collect my device (I literally held the box in my hand) there was an issue with my credit limit. I gave all the required documentation, bank statements and over four separate calls were logged to address the issue. It has been a full month now since I first found out about the credit issue but still nothing has been done. I am R155 short of credit to get the S10+ ARE YOU KIDDING ME!! By far the WORST service I have ever received in my entire life... when your own people on the ground log calls but the company still does nothing.. absolutely disgusting. There is still an open call pending for a response
