Terrible Customer Service

Had my quotation done by Wynhand Bruyns. Paid more than 50% deposit. Was promised the blinds would be ready by the following week. Kept following up and 2 weeks later nothing and kept saying he doesn't know why the delay. I informed him I will be moving in on the Friday and need it by then. He said one of the blinds had arrived for the bedrooms. I asked if those can't be installed in the meantime. When I called today Friday he says according to the factory they don't have that color. And I will have to wait another week and a half. And they can only install the other aluminum blinds next week.... All this after I have been waiting 2 weeks and they could have informed me earlier. And he knew I was desperate.
