HASSLES AGAIN TRYING TO UPGRADE

On Tuesday I upgraded online. I received a CONFIRMATION email AND a gentleman phoned me. Today Thursday i follow up only to be told that the upgrade has NOT been confirmed!!! Why send a confirmation email if it is untrue? 2 years ago when I upgraded the order was cancelled and when I followed up that is what I was told BUT I had not cancelled it. For the last 3 years I have had so much trouble with Vodacom from being de*****ed to hassles when trying to upgrade. Prior to that for 20 years no issues. What has gone wrong? Of course now Covid is the reason I cannot speak to a supervisor. Really NO CUSTOMER SERVICE whatsoever. Time maybe to change networks although none of them are any good.
