Avoid Mad Macs Somerset West

I bought a product from Mad Macs in Somerset West, which they developed, and sold in their store. I fitted it to my Kawasaki (a brand of which they are the official agents). About a year later that product failed, causing damage to other parts on my motorcycle. Right from the start they refused to refund the failed product. But was informed that they have ordered a replacement part for the OEM fender that broke. After three months of waiting, I have now been informed that they expect me to pay the full cost of the new part since the product that failed (which they developed and sold to me) is an aftermarket product! Lack of communication, and then selling sub-par products which they then refuse to support means that Mad Macs will NEVER see another sent of business from me.
