Had an RGA and followed all the instructions for the return of a defective product. It was received 2 weeks ago today per tracking and proof of delivery. I emailed Saturday to ask why I hadn’t gotten a refund and had not received a response as of today. So I called and was told that they would process my refund. I assume you have to call to get it after following their instructions? Never again. I spent $220 on a plumber who unsuccessfully tried to install a defective product. Delta sent the replacement and it took less than 5 minutes to install. Expensive lesson learned.
