MTN all round bad service

MTN network simply is terrible. I have had enough of MTN and am choosing to leave this network and hopefully will get better service somewhere else. I bought a 100mb rush hour bundle, got am sms that my 10mb was available to use. I was puzzled because i bought 100mb and not 10mb. I then dialled *141# for balances and to my surprise it confirmed i only bought 10mb. I had 1.02gb before buying the 100mb rush hour and my new balance according to mtn was now 1.03gig. I called MTN, and believe me that was a mission. Eventually i got to speak to a consultant, who kept interrupting me until i was so upset i started screaming. When i told him not to interrupt me, he was still very arrogant and asked me if he could speak. He then told me he could see what happened and that his system would only update in 2-24hrs. I reminded him, i bought a bundle that expires in 1hr and obviously bought it because i wanted to use it immediately, so how could waiting 2hrs minimum for them to figure out what happened to my bundle help me in any way. He then said he was speaking to his supervisor, i waited on the line over 10mins. When he came back he still maintained i call back in 2-24hrs. So much for service
