Bad service

Si this is my second review of **** service on the company. I upgraded on Monday and as of yet not received the promiced 20 gig data and upon asking about it getting the run around from the one too the other. As far as i know it normally is loaded the same day. Now I'm being told it takes 2 weeks. Bull****. Then I get told they can't go into my account as the consultant who did the upgrade alone can fix that. Bull****. So now i would like to know if this will be rectified today. And the other thing. I try and caal the call center and the comeback is i dont have sufficient airtime but i have 164 free minutes. Im constantly having trouble with mtn. Im seriously considering moving al 4 accounts to vodacom.
