Sales Tax exemption request being reviewed for over a week with zero response

I requested for sales tax exemption on Jul 28. The only response I got is “a team is reviewing your request”. It’s almost been 2 weeks. I’ve emailed support many times asking for status update and got zero human response. Any idea how I can reach out to the support team? Case ID: 12286150
