Online Inconvenience yet again

Once again I am experiencing an issue with my contract due to your "old" system unable to integrate my information to your "new" system. After much effort trying to perform an upgrade through the vodacom app, I received an error "unable to complete your request". I called into the Contact Centre for assistance on Saturday 02/01/2021 at 09:06,after a 20 minute long call finally my contact upgrade was confirmed. I was advised I would receive either an email or SMS with confirmation and a tracking number-after not receiving this SMS I decided to call in this morning only to be told my upgrade really was not processed!!!
