MTN R100. 00 data promotion ****

I was sold an MTN promotional package for R100. 00, at Cape Town Railway Station, but the 1Gb data was only valid for one day. Is this some kind of sick joke by MTN to rob us of our hard earned money? I was also told that I could transfer the data to my friend. This blatant lie was also a sick joke! MTN, *******ion is at the order of the day in the Republic of South Africa, and your company is part and parcel of it.
