Missing data and airtime

I called vodacom to find out why my airtime and data did not reflect on my end and why I have to purchase 1gig data every 2days even though I use WiFi at home and work. The consultant was no help and could not answer my questions. I requested to speak to a supervisor. I then spoke to Buhle joburg branch and he told me that all the data and airtime was received but could not send me an email showing all the transactions and data and airtime usage on it. He told me to go to the nearest Vodacom store with R11.50 to have it printed out. I then called the nearest store whom advised that they don't print out the transaction history and I'll have to call in and have it emailed. I advised the supervisor what I was told. I told him because of this service I'm changing network and he recommended that I change my network. This was terrible service and now I'm still left with no explanation as to what happened.
