Ten thousand calls later and still nothing

I have been trying to upgrade since last week. The initial consult didn't complete my request, something I discovered when I called to follow up. Second consultant helped me upgrade x2 devices, but got an sms to say they are out of stock and to call back. Called and upgraded. Called back to cancel because when I called again, I got assisted by the initial consult who hadn't finalized my request. I couldn't get them to fix as I had to wait for confirmation to call and confirm the request 2 days later. When I called back again, the consultant was yawning and seemd unfocused, so i dropped the call. I just couldnt risk speaking to an *********** person again. So, you guessed it, i called back again, only to be met with a message on the ivr saying they pick up a high number of calls from my number. I got a number quoted that will be charged at R2 per minute. This seems to be the end of the road with Vodacom after 20 plus years as a customer .
