Unable to get hold of anyone at Mtn to speak to

<p>I purchased the special buy 1Gig get 500mb free today at Northgate outlet for R160.00 However when this was loaded onto my ipad it only showed 1Gig 49 and not the 500mb. Also when I went onto the web page it had also started using up my data,despite not having accessed any web page. I was also not informed that the 'free' 500mb would expire at the end of December. This was not pointed out to me as I specifically asked if the whole package was valid for a month. After everything was loaded I was only then advised. The assistant then said I must give her back the sim card and she would sell it to someone else. It was made out that I was the one at fault! Not a very happy experience at all. My previous purchase was for buy 1 gig and get another free to be used ANYTIME, so naturally I thought that this was the same. Are all the service providers the same in that one never gets what you pay for?</p>
