This one contractor I dunno where he got my number from, I suspect he got it from the developer staff because we need to inform the developer if we want to do renovation. He called and offer his service to do renovation for my house. Later he came to see the house and gave me the quotation. After 2 days he keeps on calling asking when he can start. I told him I'm getting quotation from other people too and want to compare. Later he called again and start telling that all the contractors especially the one that is doing renovation in my housing area cannot be trusted, their works are shoddy bla bla... he also said that he already spend his time on me for the quotation so I should give him the project. Instead of being convincing, he actually give me creeps.. I choose someone else..
