Vegan Leather Seat Damage - Is this a glue stain or burn?

[Thithi510]

Windows were tinted recently and I suspect somebody dropped a heat gun and burned the seat or maybe it's some type of glue / adhesive? Of course the shop denies doing damage.

Anybody see this kind of damage on their seats?

Blue jeans stain?
Did you try isopropyl alcohol or spray 9 to remove it?
If it was done by heat, the grain would be melted off. It looks like a stain.
