Just to share my experience with ******:
I went to the Trend & Art of Living exhibition yesterday and met Endy from ******. I had a discussion with him on my ideas for my home, and I must admit that he seems knowledgeable. When I asked him to give me a quotation via email, he told me that he will do the quotation on the spot and ask me to look around for other quotes in the meantime.
I walked around for a while before he called me. When I went back, I was shocked by the quotation as it is so much higher than the others that I got. However Endy was a superb salesman and kept telling me how good they are and that they might seem more expensive because of the materials they use. He even asked me to bring along other quotations for him to do an item-by-item comparison. I thought that I could just pick up the quotation and go but in the end had to stay over an hour to listen to his sales talk. In the end, he asked me to sign an "appointment letter" to appoint them and put down 1k deposit. The 1k deposit can be "exchanged" for their services such as painting even if I decide not to engage them later.
As I'm not very satisfied with their design and am also not comfortable with Endy (looks like an insurance agent rather than ID), I stood my ground and did not get suckered into paying the deposit. In order to get away, I agreed to come back next week with other quotations for him to do a comparison. However now that I see so many negative comments, I don't think I will go back.
