Legitimate email, or SPAM/SCAM?

I have recently received an email claiming to be from SimpliSafe, stating that there has been a comment added to my request . . . . but I have no request in process.  The email address seems legitimate (privacy-request@simplisafe.com) but the fact that it refers to a non-existent request seems like a scam.  Has anyone else dealt with this?  I tried customer support by phone, but the automated operator said wait time is over 30 minutes (another disappointing issue altogether.)
