Pathetic service

This query with Mtn is about a prepaid contract for 30 days 2gigs , which is R279. I bought it on the 23 July 2022 and though it will end on the 22 August 2022. I received no data for the 22 August 2022. When i contacted them i was sent from pillar to post from data department back to customer care... I emailed them and still no one seem to grasp the content of the problem. I have been having issues with Mtn for a while now. They are the only Network in the area that is working properly hence i don't have a choice for another Network. If i had a choice i wouldn't hesitate to change to another Network. The most discerning about this i received an email asking for my bank account, id number ,email and Mtn pin... WHY WHY THE HELL IS THAT NEEDED.
