poor build quality and shocking after sales servic

Within a few months of buying a top-of-the line vacuum cleaner for R4999, one of the attachment clips broke. I took it to the Verimark agent in early December 2015 and as assured that the clip would be replaced (there is a 3 year guarantee on the vacuum cleaner). I returned several times over the next two months and each time was told that there was a problem, the agent in PE wasn't returning calls or that the wrong item had been delivered. On Saturday 20 February 2016 I went to the agent and asked for my vacuum cleaner to be returned to me. He made yet another promise that I would have my clips on Monday 22 February. It is completely unacceptable that a clip should break after just 3 or 4 months. This suggests poor build quality of the product. It is also unacceptable that it takes more than 2 months to receive a replacement. Considering that the vacuum cleaner was not cheap by any means, I do expect a decent level of quality and service.
