Another Mtn muckup

As can be expected from mtn, they messed up again. Last week my wife, who is the account holder, tried to load 500mb of data on my phone. The person of little intelligence who she spoke to loaded it on her phone, after she told this low IQ person that its for my line and even gave this call Centre agent my number. Why would she want to load 500mb of data on an line that gets 10GB of data and still had plenty of data left. Now because of this person of zero intelligence, we had to load another 500mb of data on my phone. Luckily this different call Centre agent had a modicum of enough intelligence to load it on the correct line. As what happens with mtn data, the 500mb of data that was loaded on my wife's line has expired, because she still had loads of other data. In other words, we have to pay for that data and it was not even our fault. Is it our fault mtn employees are mentally challenged? Why don't they track who tis call Centre agent with the little brain and deduct it from his salary. In most businesses, if mess up, you have to take responsibility by paying for the mess up out of your own salary. But as usual the lack of proper management wins with mtn. GREAT JOB MTN-AS EXPECTED
