Justin is rude and harassed me because I did not accept his quote

We requested quote from Justin for our move from Pretoria to Cape Town. He came in under budget and we were rather excited about that. Upon researching his company and finding the other bad reviews on here we decided that maybe going cheap is going to end up costing us a lot more later. We decided not to risk it and thanked him for his quote and told him we were going with someone else. He then proceeded to accuse me of being dodgy and from a rival moving company, wasting his time etc. I told him we were happy with his quite until we saw the bad reviews on here. He went on and on and on, I eventually had to block him on WhatsApp. Be wary when dealing with Justin.
