ack of service, bad attitude from staff and lack of communication

I am annoyed with MTN for the lack of service, bad attitude from staff and lack of communication as well as poor management of new contracts. Took out a new contract and new sim has been activated but no 30GB promo received as promised despite numerous calls, facebook messages & a facebook public post and all I get is a standard reply that they will get back to me and yet its over 3 weeks now and no one has even bothered to get back to me. They lack of customer care is shocking....How can you tell someone that they matter will be resolved only to not receive feedback. I am so tired of their lame excuses when all I want is resolution and I feel it fair the inconvenience I should be compensated accordingly and fairly. My 2 references proving I am waiting for feedback is 1- ********** 5396 & 1- ********** 9656. This is pathetic service and not fair that you treat customers like this. This relates to cell number ********** 951
