If the matter is now with debt collectors, it is essentially a case of waiting for a letter of claim. There's little benefit to engaging with Smart in the meantime.
Whilst waiting for a letter of claim, you can do a couple of things to prepare you for any subsequent claim:
- Get some photos demonstrating the poor signage point that you wish to argue. You should get some photos showing a close up of the terms and conditions, and some showing the placement/visibility of the signage - including the entrance, and in relation to where the vehicle was parked
- Try to find out who owns the retail park and contact them. There's a fair chance it isn't M&S who own the site and therefore, despite the rudeness of the manager, it may well be outside of M&S' influence
So that we have a record of them for future advice, it would be useful if you could upload images of both the notices you received from Smart, showing us both pages of each.
