Vodacom Theft From Clients

I have tried for almost a year to get Vodacom from *****ing R30 a day for travel saver off my airtime as I never activated it and it does not appear on my account when phoning them to ask. They keep telling me that it has been handed over to some department but to date nothing has happened. If it is happening to me I wonder how much they are *****ing from clients who are not checking these deductions.

I am based in Mozambique and if I didn't need a SA number for my banking I would just stop paying this account and wait for them to take me to court and see what the court thinks about this theft
