Anyone near Crouch End or Muswell Hill who has 'Durafold' bifold doors with inbuilt electronic blinds?

This is a shout-out for local help. My electronic controller has broken & my blinds are down. I'm hoping to track down someone else who has the same system locally & if I'm really lucky, have them pop over with their controller & one slave unit to help me raise my blinds.
