SERVICE IS APPAULING

I absolutely disappointed and disgusted by how the MTN call centre is managed as a whole. The service I received is bull ****!!!! I have been paying my contract fees for almost two years now but since Oct 2014 I have not been receiving the full package which I have been paying for. It is so time consuming to try get through to anybody at MTN because if the line doesn't cut when you are choosing the different options, you are put on hold for literally HOURS!!! when I eventually get through to someone I get sent from pillar to post. Nobody knows what the hell is going on or who is responsible for what which is highly aggravating and down right annoying. I regret ever leaving my previous service provider, cant wait to return to them. Can someone from MTN freaken respond as promised to me as to how this matter will be resolved. I have been waiting for so long for you guys to get your act together and give me a response because you are actually *****ing from me by over charging me for something I have not being receiving for almost a year now!!!!!
