Companies which do not service used products devalue their product and their brand; their products, sold used, have a lower value due to the lack of support. Denying support to owners of a used product, in order to "protect" a dealer network, places the interests of dealers ahead of the interests of owners of those products, and devalues the product itself.
I try my best to avoid such companies, and will certainly avoid Viva. Their products do not appear to represent good value, anyway.
