Bad service + rude agent

Now I understand why a customer put up a banner saying Cell C is useless. I bought an airtime for obvious reasons, to make an urgent phone call. Cell C did not credit my airtime and when I call their customer care, the lady said I must wait for 2 hours. WAIT FOR 2 HOURS?? There's is a reason why I bought it at that time. She went on to say that I should buy another one but will not get a refund for the first airtime, and went on to hang up on me. I'm switching to another network and leaving this useless piece of junk.
