Mtn are *******

The worst service ever.my mtn anytime data was depleted while i was trying to use the night Express data. the time was around 05h44 in the morning.when i called mtn they said i have linked the number during midnight to data share and that number was the one using my data so they cant help me.the worst part about this i was asleep and the phone was off.also when i checked the data share number list .that number is not even there.no messages even telling me ive linked the number.and i even called the person who didn't even recieved that data share message
