*****ING MY AIRTIME

I've had a contract phone from vodacom for not even one month and are furious already! I received my 350 rand airtime as per Uchoose 350 on the 2nd of February (which I paid for). On the 2nd I bought R 249.00 data bundle which left me with R100.00 airtime left on my phone. Made 4 calls which totaled about 3 min. Today I checked my balances just to be shocked that I only have R 5.34 left! I did the sms to see if there are any wasps services and came back negative. WHERE THE HELL IS MY AIRTIME? If this is how you ***** airtime and my money you can kindly cancel my contract immediately. I request a bill per line where my airtime has gone and for what it was used. Please do not tell me that you cannot see that Info. We all know you can.
