No data

When taking out a new contract with MTN i was advised that i will get 10gig data for 30 days for 3 months. I took it on the 4th Aug and on 8 Aug they cancelled the first 10 gig. 4 days. I complained and receive an sms in 30 Aug stating i will get an additional 10 gig data as i did not have enough time to spend the 1st 10 gig. I was suppose to get it this month. Guess What. NOTHING. I called MTN customer service on the 8th Oct and was advised that it will be sent to billing. On Monday i called again and was advised that it will take 24 to 48 hours to resolve. On Wednesday i was advised 72 hours and today 72 working hours. This was promised to me, why do i have to fight for it. Managers in the call centre said they will find out and call back. Guess what, again NOTHING. Instead some of the staff is just arrogant. We custoers for over 20 years and this is the treatment. Wow. MTN, YOU NEED TO SOLVE THIS AND JACK UP YOUR SERVICE AS IT STINKS.
