i wouldnt bother complaining to this guy he sounds fanatastic (very sarcastic). Check how the door is sealed between the frame and the masonary.You may be able to stop the leak by resealing it (silicone /mastic ), but you should not have an internal door for an external i cant say too much about it mabye there is a reason for it but the doors are made differently internals are thinner so wouldnt sit in the frame right, would give less insulation, and pose more of a security risk
