Support Stucture not in Place

I Bought a blackberry Passport phone from Vodacom last year in December in six months I had already send the phone twice for repairs. Blackberry doesn't have a support structure in South Africa. Their Web site doesn't have a customer care support service option. The phone is somewhat useless in most of the times when you need it most. It is a one application at a time phone then you have to reboot it to open a new application. Vodacom has delisted it on their contract offers and they are not alerting us that we bought a useless phone. Vodacom has to Account for this Inconvenience as we bought the Phone from them.
