WORST NETWORK EVER!!!!!

I just ended my contract with MRP-MOBILE I now use their prepaid needless to say I am not happy with the way the handle things , so I bought my mrp mobile airtime on Saturday (R100) worth got home loaded and it confirmed it was a success , I tried to make a call but I had not airtime available. I phoned and spoke to a clueless person who was not able to help she advise that I load a smaller cell c amount of airtime did just that went and bought 10 rand worth of airtime still don’t have airtime even now phoned again and spoke to another clueless person I was told that they DON’T KNOW why my airtime is not reflecting and have escalated the query , still don’t have airtime , still have not been phoned back but they have debited their money. I can’t even express how disappointed and unhappy I am.
