Incorrect information

I have a 10 gig 2mb line, on 16/01/2016 I called the call center to upgrade my line to uncapped, i was advised that my line would be R584.00 in total with 4mb uncapped and would be effective in 24 to 48 hours. I'm still waiting. Upon calling the call centre on the 21/01/2016 to find out why i run out of data I have been advised that my line speed was only upgraded and not my data. If I wanted it uncapped I would end up paying over R700.00. I confirmed on numerous times with the call center agent that R584.00 was my total amount. Now I'm unable to change my order as it is still pending on the system and i have run out of data. Totally unacceptable as to what I was advised. As per the telephonic conversation I am liable to get what was promised to me.
