To say this has been an underwhelming experience is to put it very mildly.
Please don't hesitate updating how your unfortunate situation pans out.
I've been very pleased with my Mayones, so much so that I'm deliberating selling off my other basses to put the money into a 2nd one. You've asked here in order to get some help, but you're providing a lot of help yourself regardless of how the fingerboard mishap resolves. That said, I of course sincerely hopes that it resolves to your complete satisfaction with haste.
