Vodacom issues

My name is Sharon. I've had numerous problems with vodacom overcharging my husbands monthly subscriptions fees. I've called over a 100 times to rectify the billing but to date the same issue. They have eventually blocked all my calls to the call centre and emails. They have asked me to contact toby via whsttsap and when I deal with Toby the system says they encouraging a problem and that's as far as it goes. This us absolutely unacceptable. The call centre AI says due to *****ulent behavior my calls and emails are blocked. Can you imagine this. I'm taking this further to the ombudsman.
