Blackwood Company

I found Blackwood online which we engaged with them to do a retail fitout and a coffee counter for us in CPT. We paid a 50% deposit. They installed but didnt follow drawings and specs. Snags were issued on 25 October and there has been no action and little communication from Blackwood since. When they do answer calls or emails false promises are made and there is no hope that the shop fitting will be repaired and replaced. We are at a loss on how to recover our money or to get them to commit and action the work they promised.
