Vodacom- Shocking Service, Overcharging Clients!

A colleague of mine has been calling Vodacom to try and sort out an issue for over a month now. Her monthly account is usually R249 and now for October and November they have debited R623 each month. Her statement says accidental damage insurance was added which she never asked for. She has called numerous times and the issue has still not been resolved. The one person tells her the credit will take a month to reflect and then somebody else tells her that the service request for a credit hasn't been logged. This is really shocking! Don't support Vodacom.
