Worst cell phone provider

good day guys, I would like to firstly say thank you I have had a small response from mtn but they are still breaching the contract I signed with them. My contract stipulates I must receive 500 MB of data monthly and for the last 4 months this month is the 5 th month so they owe me 2500 my of data . I have been to the stores just to be told sorry they can't assist me a complaint will be lodged. I have received no phone call no e mail the service is absolutely shocking and I can't wait to cancel my contact never to return to MtN again! Now I receive 500 MB of data I do t knowing f it is then or maybe a family member who u der stand I am struggling at the moment. I want a phone call from a manager explaining to a client \me"who have been a client for more than 10 years why the service is so bad. They owe me my data and a apologize to me. They will quickly phone if I put a stop order on my Debid order that I can promise you but I am getting completely ignored for 5 months ! I wonder if there staff are being paid as badly as the custemors. My greatest desire will be to cancel our contact with MtN and to advise the whole of SA to stay away! Thank you so much Danielle and Duard Kilian"""
