Was it installed with vacuum or without as is the case with most Installations.

without vacuum. as technician do

This is the reason. It wont go down. The refrigerant has been adulterated with air. Either the whole refrigerant is changed and that too one that you buy yourself and not the ones these technicians carry because that too will have air in it. And than finding a technician that puts it using vacuum.
