Openserve deactivated Vodacom clients

Openserve deactivated our account through Vodacom.... for no reason. They do NOT have capable people to help resolve the problem. Problem has been for four days with no answers from Openserve or Vodacom. Vodacom now cashing in as client need to buy data, as Openserve Unlimited is not working. PATHETIC.... WAKE UP!!!!!
