Vodacom cant resolve customers queries

Hi,i have two contracts with vodacom,the other one is for my 5 years old daughter,she only receives 400MB for games ,i pay R390 for both contracts,to my suprise R680 was deducted in June,i called vodacom to find out why,and they explained and helped me to disable the apps they claimed to have increased my premium,in July R850 was deducted i called them again to find out what happened ,they told me the same story which i thought we sorted out in June,then i went and reversed the money,in August they deducted R1 700, i went to the Vodacom store in Brits Mall,the consultant told me the same story i have been told,i cancelled my daughters contract since it was due for upgrade and i was cancelling it for the second time.

This morning when i wake up i couldnt make any calls or receive messages,i went to vodacom they told me my account was in arrears and was suspended ,Now the amount i owe is R 2 700

I really dont understand why they are doing this to me ,i have been with them for ages ,i never missed any payment.and when i try to ask them what led to that amount they tell me my daughter a five years old has been hospoting other people ,but they cant give me the numbers she hosposted. They tell me she loaned data and staff like that ,my daughter cant even write her name shes too small to be able to do all that.

Please assist,what if her account is being hacked,and if Vodacom cant help ,who should.

Im depressed
