Openserve clients being deactivated for no reason

Vodacom clients being deactivated on Openserve wifi for no reason. It has been four days with no answers, and meanwhile customers are forced to buy data.... think this is a nice **** from Vodacom to force clients to buy data.... as their wifi unlimited from Openserve has been disabled. And Vodacom doesn't have any answers.... this needs to be investigated. They don't even have reference numbers for complaints to be followed up.
