Payment Process, Call Center, MyVodacom not working

Received message that my "debit order" was successfully canceled. I have no debit order, nor did I cancel anything. Service suspended. Found that my credit card had expired. Called the recommended call centre number, followed the voice menus. Had to enter my cell phone number multiple time (!) in the process. Eventually, the call crashed and I was thrown off. Repeated the process. Same result. Went to "MyVodacom" site. This is one of the most disgusting and dysfunctional sites I have ever seen. I can write a book about all the stuff on that site that simply does not work. After lots of fiddling I eventually was able to supply new CC details. I then tried to make payment. After entering my OTP, I was transferred back to the Vodacom site and the payment process crashed. I had no indication whether the payment process had gone through or not. Tried again the following day, same result. I have now wasted lots of time and effort with no result. For many years, Vodacom has proven to treat their customers with contempt and out of all companies I have done business with in my life, Vodacom ranks as low as you can get with an utterly disgusting attitude and track record.
