Angry customer

I would never of thought I would write a bad review about vodacom but today I just had it... I purchased data on my vodacom app earlier this morning the money was taken from my account but I did not receive any data I even tried to buy again as I need data again money was taken from my bank account but no data allocated to my number... Customer care cant help me because there is no order number... Is that my problem I've got my bank stament to show the amount was taken. I hate this...
