Vodacom telling me their *****-up is not their fault is the last straw

I am so disappointed in Vodacom. Been a customer for years, worked closely with Vodacom. But now your customer service has gone to full-on junkstatus. I've upgraded two weeks ago, got the new phone eventually last week Thursday, but no new smaller sim card. Even that I can accept, but when I phoned the call center and was told IT'S NOT VODACOM'S FAULT, I just lost it. Of course it's your fault! Don't tell me bull. Vodacom can clearly see each and every user's current phone use, sim card number, size of sim card.... And if you had any intelligence left in the company you'd check what sim card the client is using before sending the new upgraded phone, as you also can see what sim card is needed for the new phone. When I kindly let the lady at the call center know that I knew this, all she rep**** was "Oh". I was beyond crazy mad at Vodacom, now I'm just over it. This will be my last contract with you. I wish #NashuaMobile never pulled out of South Africa, would have done better and better every year as the South African networks go from bad to worse.
