MTN South Africa - Biggest Data & Airtime ********

They barely deserve the 1 star. I loaded R62 airtime via my bank which just disappeared out of nowhere, when I query they tell me I was using out of bundle what what which doesn’t make sense to me cause just after I loaded the airtime I meant to convert the airtime into weekly data bundle and didn’t access any apps, the only app that had mobile data on is WhatsApp apart from standard apps that don’t require a lot of data usage. MTN claims my apps consumed my R60 airtime and specifically my Twitter app which comes as a surprise as i have been logged out of Twitter for a while and even it’s mobile data has been switched off. It isn’t the 1st time that MTN depletes my airtime for absolutely no reason and the excuse that I have apps running in the background just doesn’t make any sense when I actually do not have apps running in the background resulting in depletion. MTN took my R60 airtime and I want it back, how can apps deplete R60 when I didn’t access any? I am switching as soon as my contract ends!!!!
