Don't waste your blocks on this number unless they are using it to  call you more than one time. They are changing numbers frequently and will just call you from another number. They have tried peddling everything from security systems to vacations to credit card interest rates. Numbers they have used are 904-435-0851, 904-435-0826 and 904-435-0821. There are also others.

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.
