OMG!! REFUND WANTED!!

I have been using my data ****le for nearly 3 years now - I always load my airtime on to my sim card to recharge but in the past few months I have problems where my airtime disappears(happened once before)- please note there were NO other internet explorer or applications open at the time! I loaded over R200 to get 3GBs of data but when I tried to use the vodaphone internet application to do so, it swallowed every cent and I never got to get my 3GBS. <br> I spoke to Mwabe from the call centre, I was told it was my fault because I was using the internet during the course of recharging. So she was ****ing me off and I told her this because she wasn't listening and kept interrupting me! She told me that I was swearing her and gave me horrible attitude and at the end...I wasn't helped. This is happened before where I tried using the vodaphone data application to recharge and last time I got my money back. Now I invested a lot more money and now I wont get it back because it was my fault my airtime disappeared?? I want my money back to load the 3GB that I need for internet otherwise I will cancel my cellphone AND Data contract quicker then you can blink if this is NOT sorted out TODAY!
