I have had this on a '99/T Mondeo, I fixed it by just kneeling on the seat back and repeatedly wiggling the seatbelt in and out of the top of the seat until it freed I'm afraid.
At the worst you will only have to undo the bolt holding the belt end to the floor (size 10 star bit IIRC) which will allow the belt to retract far enough for the inertia reel to release.
