Vodacom Service Purely Pathetic

I recently bought a Samsung 8 watch from Vodacom Bedford Square. After the 1st month the watch battery did not last more than 8 hours. I have already had the watch booked in to the Vodacom repairs shop on 2 occasions and the problem has not been rectified. The watch has now gone back for repairs for the 3rd time. So in under 3 months the watch has been sitting at the repairs centre for more than 45 days. Nobody at Vodacom wants to resolve this issue. The service is pathetic and getting someone to take ownership is pulling teeth. Shame on Vodacom for such a painful experience
