Utterly dissapointed with Vodacom again!!

A few weeks ago a Vodacom consultant called me to offer me a "free" upgrade of my data package from 1G of data to 10G of data for the same price AND the same number. I thought this was wonderful and agreed to this. Low and behold this was merely a **** and on my next statement I was whacked with another R200. Nogal the new sim card was not even linked to my old number and when I called a Vodacom consultant they suggested that i need to buy another sim card. I am utterly frustrated with Vodacom and if they really cared about customer service they would get somebody (that actually knows what it's going on) to call me ASAP! Pathetic!
