Four Hands Carpentry

Does anyone have any ideas what to do with the company "four Hands" who I have a contract with for the provision of furniture within 80 days of first payment.

Now we are at day 210 and still I do not have all my furniture yet I have paid for around Baht 1.1 million out of Baht 1.2 million but the outstanding items are worth much more than the 100,000 I hold.

Is there any quick way to get him to complete the job as my family will come down to Pattaya for a two week break and the dining table has no top, no chairs I only have one bed (I need four).

I NOW understand that "Four Hands" always do this sort of thing and so far have got away with it - am I just to add my name to the list or is there a quick fix
