Econavitas - bad service and lack of customer care

We bought an expensive solar geyser from Econavitas approximately 3 years ago on their recommendation. We received bad service from them from the beginning. This bad service and lack of care for the customer continued when our geyser burst last week. Despite our 5 warranty we were simply informed by Econavitas that we should institute a claim under our household insurance as (a) the supplier, Nobel, has left the South African market and that they cannot supply a new tank under warranty and (b) Econavitas no longer supplies residential solar geysers. Please stay clear from Econavitas and consider alternative, customer centric suppliers and service providers.
