Upgrade shambles

I called on the 22/01 to cancel my contract, but was offered a 'good deal' to stay on, after 18 years!I was offered a S9+, purple as it was the only one in stock. After a week of non-receipt, I called again and was advised that the phone is not in stock, and is on order. So I changed the color to blue. Still no receipt of phone so called again, to be told that there is no blue, but Titanium is available. NOTE, THIS IS THE 3RD call I've made. Then, on the 12th, still no receipt, I called for a 4th time to be told the phone has been discontinued. Whats irks me is that I've had to call every time to be told the phone is not available. Your guys [process is completely flawed. Either Vodacom as a company is ***********, or its the consultants. And then I get offered an inferior option to what I was meant to receive. After 18 years, is that what customers can expect from Vodacom???
