Boss paving Durban terrible service

I recently used boss paving to pave my pool area. The paving was done well but they completely destroyed my pool ! I watched them paving and they did not care at all how much sand, cement and stone fell into my pool. They knew it wouldn’t be their problem . My creepy is sucking up stones and rocks and a week later of having to refill the pool with water every single day we still have cement, stones and sand at the bottom. I understand some sand would get into the pool but not this quantity. Surely if you specialise in residential you look after people’s pools while you doing the job. It is so rude and disrespectful to leave a persons home like this . I spoke to the owner and he just said that’s what happens when they pave a pool area. We paid them R40 000 to pave and bow we have to pay thousands more to repair our pool and for water
