Dangerous products to sell to people

Rocotta Brick centre in Polokwane sell very poor bricks to the costumes and they don't even care about thier services. I reached out to them complain, they just gave me a wtsup number and said to me that I should send pictures to wtsup number and they will get back to me, but they never did. Thier bricks malt up when it's raining and fall off.very poor quality and dangerous, put life of children in risk.
