Contractor stop all the work and lock my house dont want to give me the key ( grill door key installed by him which i don't have)

main reason is because he is unhappy with me for criticize him on his work :wrong air-cond electric & copper piping , wrong light point , coring wrong size, delivery time problem.

No communication from him, when facing problem he didn't discuss with me then himself sort it out change the design without informing me.

Supposedly everything including kitchen cabinet must be delivered this month, since he has resources problem i already tolerated with him to deliver the plaster ceiling by this week and kitchen cabinet can be later but also end up with this week he didn't do anything and didn't inform me that he couldn't deliver it by this week until i find out.
what action i can take now ?
