Rip-off artists

I got these guys out two years ago to make and instal a pool cover for me. I was happy with their work. In the meantime I have repaved my pool area and asked them to reinstall the cover i.e install the plastic clips that the cover hooks into - there are 20 of them. They told me it would cost R3000 to do this. The full job last time, including the manufacture of a thick PVC cover came to just over R4000.

This is **************** and it's absolutely disgusting! They are clearly not interested in follow-up customer service and are just out to make a quick buck. Avoid this company at all costs.
