Returned back from a late lunch and discovered someone from this number called my work phone twice (once at 12:49 PM and again at 1:14 PM). No messages left. I do not have any accounts with Comerica Bank, and I have had this same work phone number for nearly 10 years so I'm not sure why someone from there would be calling. If it was important, they should've left a message. That leads me to believe it may have been a sales/telemarketing call.
