BAD ADVERTISING FROM MTN

Poor advertising from MTN... Regarding the SIM ONLY DEAL - The total value of the deal is 140GB (70GB an 70GB night Express). The 'BONUS VALUE' 30GB anytime data and 30GB night Express data, but according to them the BONUS VALUE is included in the deal, since when?? From the first start we haven't received the correct data and I've been in the shop every week... and still waiting for them to contact me. I'm very disappointed as I've been an MTN client since I have my first phone.
