Impossible to speak to someone to rectify a problem

I want to give NO stars! I tried to buy data yesterday for my daughter at boarding school; I tried via the cellphone app and later tried on-line; I also tried bauying airtime 1st and the to use the airtime to pay for data and a few times tried to just buy data directly but every time I was kicked out with the message Payment error try again later. and I tried a number of times. Last night I had 6 debits on my bank account for airtime purchased with NO airtime reflecting on my daughters' airtime balance and 9GB on her data balance. I definitely don't want her to have so much data available and the numbers does not make sense in any event; much more debits to my bank acc than what 9GB data would have cost. I have tried phoning every customer care no. and either gets cut off or I have no choice for a language selection and have to listen to a language I do not understand. VODACOM is fantastic until something goes wrong, and when something goes wrong it appears to me they make it soooo difficult to get in contact with them, that the customer just gives up. ALL I want is someone to speak to and explain what happened and I need my account to be rectified!
