MTN de***** client

MTN refuses to load data which i paid R449 for. They say I forfeit my own money.They are keeping my money but not furnishing the service i paid for. I have been ******.I paid for a service and it was not rendered. Is this standard business practice to swindle money out of hard working citizens?

I have engaged with their call center staff on different occasions regarding this matter and they promised to rectify it, only to be told today that I will forfeit my money and they are not going to load the data.
