After reviewing our support records, I do see three emails from you regarding rebates, however I also see responses to these interactions from our support team. Is there a chance these responses are going into you spam folder?
Also, to resolve the issue with the rebates, this rebate is actually processed through California Water Services. I did some digging, and on page 3 of your application near the bottom of the page, there is an address that you mail your application into to start the process of getting your rebates from your municipality. Hope this helps, let me know if I can answer any other questions!
