Missing airtime and bad attitude

So I last checked my airtime yesterday and I had R20.00 and about 20something MB left then I made a short call and thats it. Then today I try loading a page and guess what it doesn't load! Then I check my balances to my shock its R0.00 and I have .9MB left worth of data yet I never got the sms notification about my data running out soon! I called customer care around about 19:47 and spoke to a lady that did not give me a clear answer and thus I asked her to end the call so that I can rate her service but instead she transferred me back to the main menu where I couldn't even select the option to speak to another consultant to report what she had done! She made me feel stupid for even thinking that the rating of her service would do me some kind of justice! December I didn't recieve my airtime and I let it go because you showed that you regreted the incidence and gave me what I intially wanted to buy BUT this month MY AIRTIME finishing without warning coupled with UNPROFESSIONAL BEHAVIOUR??? That is too much! No, this is not on at all!
