Is it occur to cut top cut off a new upvc door frame and install without cill?

Hi, a fensa registered company measured, ordered and installed my new upvc door. Unfortunately the door frame was too high. So the installer cut 2 to 3 cm of top of the frame, (so you could see the hollow frame from top) and said it was ok as he would put foam on top and silicone round it. He was also unable to fit the cill under the frame and just said it was not required (so why was a cill provided?). From what I can tell when I put underfloor heating and tiles on the floor, the door which sits on the outerbrick will be an inch lower than the floor. Is this ok? Does cutting the frame compromise the door or frame in anyway? Does it weaken the structure, allow moisture in etc? What is the purpose of the cill if its not required? Does it prevent water ingress? Is this an acceptable practice from a fensa registered co. If not should I involve my building inspector if not what are my remedies? I m looking for advice and info before approaching the contractor, so thanks in advance. I m baffled as to why a made to measure needed to be cut. Update: to be clear the door has not been cut, it is the top of the surrounding frame - i am assuming thats still not great, but not as bad as cutting door. Secondly the contractor is saying it is a low ali french door and therefore does not need a cill. I obviously am not an expert on this to contradict him. So who can I involve to arbitrate. Does fensa provide arbitration, or can my building inspector check this out, as its a new extension
