THEFT - AIRTIME

I have a top up account which i have had with Vodacom for years i actually can't even remember must be close on 20 years now which i use for my father. @ the end of June my debit order went off my account but my father that is the user of the telephone number in question only received a portion of his airtime well less than half of his airtime. i then called vodacom and opened a case and to only follow up on the case now to be told to read the T&C's, what does *****ing airtime have to do with T& C's. Vodacom took their money out of my account but did not allocate all the airtime to my father's number! unacceptable. I'm sure the media would love to hear from me. VODACOM I EXPECT YOU TO CORRECT THIS ERROR SOONEST!
