Do they have a Facebook page? Try complaining there

I got no problems with SK but I did went to three branches before the last one were willing to quote me exactly what I wanted.

Everything done very professionally. My only complaint if any is that they dont have proper tools to drill the hole for the backboard so that they can pass the wires through. I wish they drilled the hole more nicely and put a grommet or something. Just a small cosmetic matter.
