Poor customer service

I recharged myphone with R60 airtime an hour ago, and switch off mydata as I was advised before by MTN consultant. When I buy Whatsapp data for R30 it does'nt allow me as I don't have enough airtime.

I called MTN customer care and the guy by name of Vukile apologised and told me to switch off my cell for few minutes and when I switch it on again my airtime will be there.

To my surprise after switching off my phone and put it on again I only have 0.38 cents. I called MTN again and this time around spoke to Phindile who explained that system show R21 balance that is not showing on myside. Her system also shows that I have recharged with R60 but she doesnt know where the whole airtime went and she see R23 used by network(data) connection but the rest she doesnt know as system update after an hour.

I am not happy and this is not the 1st time this happened.

I hope MTN will upgrade their system not to rob us as customers.
