Vodacom do not comunicate on their sistem

So last week I upgraded an exstra contract I have with vodacom that expired in Feb already, then the phone was dicontinued and no one could help me with cancelation. As I need a device cause mine broke and my original upgrade is October. I am borrowing a phone. So after alot of useless phone calls and complaints one lady assited me and got me the cheapest deal on a S21 so I took it. That was ons Thursday. Today I got an sms and email from the CEO office email that all has been cancelled.... WHAT? WHY? This just shows how useless vodacom's system is.. I dont know anymore. I give up.
