The tech didn't showed up for the appointment during a whole day waiting timeframe.
The next days I got several calls from the Sears automated phone system letting me know to call back the same automated phone system!
I did, but a life person was never available and there was no option to cancel the service call, only to reschedule!
Fortunately I have Project Fi cellphone service from Google, so I was able to mark the Sears automated phone number as spam and block it.
