Hey TS you are certainly not alone here. I have heard too many stories about IDs failing to deliver their work and going missing over the past few months from friends and relatives around. It does seem that there is an increasing trend in such unfortunate issues.

One of my close friends who had to go through this ordeal is still having PTSD thinking about the possibility of her family having to re-do the entire renovation and the financial damages which they have to bear.

I would suggest you trying to go to CASE, but from other homeowner's feedback in the forum there doesn't seem to be much CASE can do.

You can also seek legal action against your ID if any of their undeliverable or delays have violated terms of the contract of your project.

Hope all is going well for you.
