    Welcome to the forum. Where did you get your brakes repaired? as I cannot see a proper garage sending out a vehicle with a defective hand brake, thats terrible.!
    Are you aware that the wee shoes operate inside the rear discs and operate on a ratchet wheel system, adjusted through a hole in the brake disc. The system is pretty basic, but adjusted correctly does work.
    The normal reason for the shoes not biting is that the they have been adjusted while the cables are still tensioning the brake shoes.
    Proper way is to disconnect the cable, adjust the ratchet wheel with a screwdriver through the hole in the brake drum until the wheel locks an then back it off a smidgen so the wheel rotates and then do the other side in a likewise manner. Only then connect the cables and adjust them as necessary, greasing all the pivot points. The hand brake will then work providing of course there is no major wear to any other parts, such as the pivot pins where the cables attach. I would assume that any garage worth its salt would have identified any worn components and replaced them as necessary. Because the cable do little work they generally do not stretch very much, only seize up from lack of use.
    Hope you get this sorted soon.
