Not sure if this is in good faith or not, but escalating through an internal contact is going to skip a couple layers of support at minimum, and reduce the chance of a misunderstanding. Also potentially some people in CS might be in on whatever is going on.
If you were being snarky, it seems like this LinkedIn employee is trying to do the right thing. They probably don’t run support/there’s no reason to take cheap shots when they offer to help.
