Change In Scope Of Minor Reno Work

[tgtmbelief 0]

Dear all RT forummers,

Need help to resolve issue with contractor. Appreciate anyone here can share ideas. I have reached a dead end, trying to negotiate with him. Initially, my scope of work is reposition kitchen sink, kitchen cabinet & washing machine water inlet/outlet pipes and new electrical point. Having agreed on price, after bargaining down, I paid a deposit and got an invoice with the above scope of works (written in chinese which I can't read).

My question is, at this point in time, can I amend the scope of work? The contractor is very unhappy when I brought it up and said he refuse to take on the new scope. Must say that the new work scope is sized down quite a lot. Is that a legitimate reason for contractor to turn down job and forfeit deposit paid?

Please share your thots...
