I finally received confirmation from Tesla that they will send me a check in 8 weeks. This took 4-5x emails and 3-4x phone calls and what finally did the trick was checking the "Escalate for Executive Review" box on the website. I really didn't want to check that box (figure its for REAL problems) but alas they made me do it and apparently it worked - took less than 1 business day from sending an email to execs until i got a response.
