I've never had any business with CompUSA in any of its forms. I have been inundated with calls from them. No messages. I'm on the National and Florida Do Not Call Lists. I'm assuming it's a scammer.
I, too, received phone calls from this number as well as various 904 area code numbers. They never leave a message. I never screen my phone calls I always answer. These call seem to only call during the hours I'm at work. Therefore, I have no idea who it is.
