Just had my rear windows tinted and the person who did the work neglected to use trim removal tools to loosen the door cards to remove the window seal.  It'd be a fruitless endeavour chasing them to sort it, so I'm looking to at least try and repair it myself.
Basically the soft material at the top of the door card was ripped vertically, leaving a 50 - 60mm tear.  Any suggestions on how to stick it back together or at least reduce its visibility?  I know it's a tall ask without having a reference to go by but I can add a photo tomorrow morning when it's light.

• I've added a few photographs. 
• Key for scale reference

In the yellow circle photo, it is very difficult to see at a certain angle but it very visible from all other angles (as it's all I can see when I'm sat in the drivers seat).
