Substandard service by Ecars

On the 10/12/20 my car's fanbelt snapped and I took it in for replacement&servicing at Ecars in Welkom .To my dismay on the 05/01/21 same fanbelt was worn out. I called Ecars WELKOM to report my terrible experience.Unfortunately I was sent from pillar to post .I then resorted in contacting Ecars Head office.They contacted WELKOM office but it transpired that they blamed me for the snapping of fanbelt citing certain car parts that I needed to pay for which were never even mentioned to me on the day of the service.Ecars heard office refered the matter to Retail Motor Industry Organisation for mediation .When I contacted them for progress on the matter they informed me that Ecars WELKOM is not providing feedback on requested information causing delay in finalization of the matter. Iam very frustrated without a car since 05/01 21 .I wonder if the fanbelt they replaced was not a second hand part?
