I thought that that tech. support didn’t return my phone call. Then, I looked at the blocked phone numbers in my iPhone and found the message that they returned my call. The Rachio phone number is unidentified. We get so many SPAM calls that I don’t answer unidentified numbers. Admittedly, I’m old. I think it is common courtesy to identified the caller.
Tech Support did their job. It is the phone system that is failing both of us. Bad reviews for tech support and disappointment and frustration for installers.
