The worst service I have ever received

MTN is the worst network provider with the most pathetic customer service. It seems they are running a circus. I just took a new contract with them which included data, sms and minutes. I started off with 270 minutes but the next day it went down to 110 minutes and later that week the minutes disappeared completely without me using it. I called the service center and was told there’s no call log for those minutes so it will be investigated and feedback would be given in 7working days. Furthermore I was told to fill airtime on my phone at my own cost by the service agent!!!! I have a contract but I need to load airtime at my own cost to make calls.... their ***** ups must cost me!!! Furthermore I have called them 3 times for feedback and a full 3 weeks later all the agents I am speaking to doesn’t have a freakin clue what’s happening and in this month while they are robbing their customers I must waste my time and money chasing for what’s owed to be and paying more than double to constantly be filling airtime! They are the most sloppy and pathetic network service. I have never had this problem with any of my other contracts from other network providers... does mtn think we have nothing better to do than to chase after them for feedback???? To take a contract you will get endless unnecessary and irritating calls from call center agents but once you tAke the contract they rob you and treat you like dirt and will never give you feedback. For the entire month of August I did not have my minutes and that is a breach of contract and that is *******. I’m so furious and frustrated with the service I even told all my work colleagues not to take their new contracts with MTN because they are the worst and my colleagues are now enjoying their phones from other providers while I’m fighting with this useless and *********** network!
