Anza Flooring Durbanville - refund unpaid after more than 6 months

Anza Flooring Durbanville laid flooring for me over 6 months ago. When lifting the carpets we found beautiful parquet flooring underneath it in some rooms. It was agreed that they would not lay new flooring in those rooms as they could easily take the material for the new flooring back to the supplier. They undertook to refund me the difference from the significant deposit I had paid. Over 6 month and numerous promises from them but no refunds have been paid, every time I go to the shop and ask for my money they say they will pay that day or the next and nothing happens. They also promised a quote for restoring the parquet which was never forthcoming (I eventually simply did it myself) and they also broke an antique overhead light, presumably with the long boxes of flooring. I would suggest to people researching them to save yourself a lot of aggravation and spend your hard earned money elsewhere.
