Being left in the dark

I recently upgraded my cell phone contract at the Cell C in the ********** I chose the package that I wanted and thought the upgrade process went quite well. However, when I was upgrading I asked the woman who was helping me if i will be receiveing my Data for the new month ( I upgraded on the 5th of August) and she told me that i will be recieving a portion of my data for that month (obviously as i upgraded into the month already), However i have not been receiving the aditional data that she said i would be...which is now a problem as i can't go through the month with only 250MB... so why tell me something will happen and then it doesn't.

While i was busy upgrading i also asked her if will be able to go over my contract amount every month and she said no, which is great for me because i was prepaid before and prefer to control it rather than it charge me rediculious rates if i finish my data or minutes etc. About a week later i started to realise that i was being billed forsomthing but was not sure what it was because i did have both minutes and data... turns out that i can't make calls to certain number without being charged...WHICH I WAS NOT TOLD! I then went to cell C in centurion mall and was informed that a R200 limit has been added onto my contract which i can go over with (which she told me would NOT happen)!!!!!!

Thirdly, when i upgraded the woman that helped me did not inform me of what i will be paying and when i will be paying it, My contract is supposed to be R800 and now it ended up being R1300... HOW THE HELL?? .. it turns out i am being being billed for a bunch of things at once (which i will pay) but it is rediculous how you guys have such bad communication s****s with your customers.... I've wasted so much time, data and minutes trying fo figure out things that should have been told to me!!
