I'm currently disappointed with Webuycars Silver Lakes' handling of my complaint.Despite escalating the matter to the Motor Industry Ombudsman of South Africa (MIOSA'), Webuycars has failed to respond as required.The investigation is on going ,but Webuycars' lack of cooperation is causing unnecessary delays, it's clear that once they receive payment, customers' concerns and complaints are ignored.The customer service is appalling,with staff that are disrespectful,unprofessional and showing no regard for customers.
