HORRIFIC SERVICE HAVAL CAPE GATE

This dealership made me book my car in for a full day because my window wipers were not working properly. They needed to do a diagnostics test. At the end of the day my daughter collected my car and they said nothing. I whatsapped them on the number they were communicating on whole day with no response. I needed to understand what is wrong with my wipers and asked for a quotation to have it fixed. A day or two later i called them, asking to speak to the Manager. They put me through to Gerhard. He apologised profusely and promised to get back to me. He did not. A few days later i called him again, same thing he promised to get back to me - nothing. I emailed the complaints line who then emailed Gerhard. No response. I followed up again, no response. ***???? I Seriously fail to understand the lack of service. My motor plan has expired in may - and? What is the reason you cannot send me an invoice for the repair of my wipers????
