Stay away from Zambezi Builders warehouse - Pathetic staff and service.

I ordered building material on 23-01-2020 online and received confirmation that these items will be delivered to me on Saturday 25-01-2020. Saturday afternoon I called the central number and they put me through to Builders Warehouse Zambesi, where i was informed that they will only deliver on Monday 27-01-2020. On Monday 27-01-2020 at 15:30 they called me to inform me that they have loaded the truck and they are ready to ship to me. So i informed the lady that the delivery was expected on Saturday and no one was able to accept it now. So the lady agreed that it would be shipped in the morning, I explicitly told her before 11:00. Then she added, the 10Mpa Cement bricks are not in stock, but they are sending the 7Mpa bricks which is exactly the same ??????????? so why are they de*****ing the public by selling 7Mpa with 10Mpa prices ????? - So after about 30 SMS's and E-Mails on credit notes and charges we are now at 28-01-2020 13:00 and they call me to ask me for my address ???????? - @ Builders Warehouse Zambezi. You are pathetic, beyond pathetic... I will by at your store today to collect my full refund and I will be sending you the invoice for the costs i uncured due to your incompetence. Please fire all your staff and start with people who knows the difference between 7Mpa and 10Mpa and what impact it has.
