Why should I pay for data I have not recieved

It cannot be right that MTN can bill me for data I have not received or used. I have been calling their customer care for the past 3 days to find out why they won’t load the data and they say my query would be attended to within 48 hours. This is the 4th day and I still have not recieved my data. Now I’m expected to pay for data I don’t have. This is ridiculous!!!
