Mtn tsotsis

I signed a contract with Mtn on the basis that I would pay R299 per month and receive a router, sim card, 15gb daytime data and 20gb night express data per month for 24months. 5gb(daytime) and 10gb(night) being promo data as advertised per month. After 7 months..7 MONTHS!!!!! the data started running out prematurely, so I went to a branch just to check what is going on. They tell me that the monthly promo data(15gb) hadn't been loading from the start of the contract, so in other words I was sold a contract that provides me with 35gb per month but was only receiving 20gb. It is now going to take 5 business days to create a ticket and to resolve this issue for me, a paying customer, to receive what I have been paying for but never received 7 months down the line. I asked if they will credit me with the lost data that they promised but never delivered and the answer was that it is "promo" data so no, they cannot. They can only fix their "mistake" going forward. In conclusion, if I hadn't queried my contract after 7 months, they propably would have continued having me pay for data that they never loaded..be very, very carefull of MTN, their promos seem attractive, but they take chances everywhere they can, to ***** your money.
