sorry to hear this, I think bukit tengah is a bit not easy to bail out.

have you tried quietly talk to the developer saying you want to bail out and mentioned lets settle this quickly and quietly. u can even pretend to ask about what other new projects the developers are doing and near or already completed and if you can get those instead etc. as to show your intention you want to bail out but flexible to hear their options.

at the same time, get a lawyer to advise what you can do fast ! now that PR is in charge, u may go find any lawyers who are link to PR.

lastly go to development board also, i don't know if seberang prai still fall under Penang dev board, but the last time I went to PDB, they can give quite good advices for this kind of cases.

good luck buddy !
