(480) 636-2320 was a Messaging System Calling
I just signed up for DHL online. All of those messages above say that they are DHL. Another app, Hiya, states that that number is DHL. YouMail automatically blocked the number. I have important business to conduct. I believe that number probably is DHL.
I signed up for an account and they are following up. Not sure I would call this spam since it's not a cold call.
This is a DHL call center. I registered for an online DHL account three days ago and then received this call today
