From my experience support sucks in most casinos... I am not sure where they find those guys/girls and how much they are paying them, but sometimes they can be a real pain in the ass.
Most single-brand operations outsource them to a CS provider, and the CS provider can sometimes be a random one.
Multi-brand operations without a parent company also outsource them.
Multi-brand operations with a parent company (like DAMA N.V., Betsson and similar) have their own customer support team.
Crashino is a single-brand unlicensed casino, so I'm guessing they outsource everything.
