MTN BAD Pushed Notifications

I just recently bought mnt sim. Sadly I'm not enjoying it at all, when get any call then trying to drop the call, there are always notifications that a displayed directly on the drop option button. This notifications are automatically forcing one to access 5/day games or something that charges me. When I buy airtime, my money disappears and it is annoying When you can't get your money back because if I want to gamble, I know exactly where to go. MTN must stop *****ing my money period.
