Plastering & Rendering

uneven joists have meant the new plastered ceiling is lumpy, any advice on how ways to rectify this?

Hello, we are redecorating our L-shaped open planned kitchen/dining/living room. Our ceiling was originally artexed, the plasterer and his team took down the plasterboard (partly to give the electrician access to the electrics). Once electrics were done, new plasterboard were put up directly onto joists and skimmed. However the finish was not level, with the ceiling having one very noticeable ridge where one particular joist is lower than the others and a crack appeared across the middle of the room. The plasterer returned, added another layer of bonding and re-skimmed with a "thicker" layer of plaster in areas needed. There is now not much of an obvious point, but the ceiling is even more uneven and at some points when lined up is out about 4cm. I am very unhappy about this, and originally requesting that this is remedied using a batten and plasterboard method however they have said we will lose about 40 cm ceiling height and so this is the best they can do. I would appreciate your advice - are there any other options we can consider for a smooth straight finish?
