HAVE NOT RECEIVED MY DATA FOR 6 MONTHS

I've been having a problm since April with MTN. I am struggling for 6 months with stors to help me to solve this problem. Then I only get service requests thats being logged. And then I get an SMS with the ref number, after 2 days I get another SMS saying its been resolved. When I check my balances I STILL have not received my data. SO how is the problem resolved?!?! I went to stores in Baywest, Greenacres AND REGONAL OFFICE in Cape Road to assist me and then they cant even help me. I am sick and tired of this. I honestly do not know what more to do. I pay R650 and more for this contract because I need to buy my own data every month. I cannot believe this service I am receiving. This is really ****TY. ****TY customer service!! Whats the use of Customer Care and Regional Office or even consultants in the stores if NO ONE can help you. I email customer care. They tell me that I am receiving the allocations but then I go to the stores for assistance and regional office for help but then they see it for themselves, but guess what they just keep on logging service requests. I am honeslty SO frustrated I do know what to do anymore, because honestly I do not need this simcard at all. The phone is way more use for me that the simcard. I am feeling so helpless ,because no one can help me. WHY IS THAT?! I dont know who to talk to or where to complain anymore about this. Its my first contract with MTN, everyone said they so good and great customer service that is why I went to them. But honestly it was not worth it. This is my first and last contract with them. I wanted to add more lines to my account, but its not worth it NOT WITH MTN. I am very disappointed. I pay my account everymonth. I am never late on payments. But this is the service I receive. I have so many ref numbers I cant even count them on my 10 fingers! SO disappointed, my whole family is with Vodacom. I honestly need someone to sort this out, I dont know what to do anymore. USELESS!
