Dear K. Opad
Our Thai friend told us u called her to ask payment of the 100000 Thai bath invoice attached.
We don't understand well why we should pay an extra design cost, since this sketch up 3D is the one of the actual design approved by the land office: we think the contract included the sketch up 3D of the approved design.
When we read ur invoice, we thought u propose an improved 3D design (for instance with real colors, and so on...), and asked us for approval of this extra work. We did not answer approval for that, that's why we did not give u the 100000 THB.
Of course, we understand that any future change from the approved plans should be charged by you.
I let our friend call u back to clear this situation.
Best regards
