Phone Staples because they're responsible for delivering to you the rebate they advertised.
The easiest way to speak to a live human at Parago/RebatesHQ is by phoning their escalation dept. at 1-877-681-2362.
I did talk to the Parago ppl, and they asked me to send them a written request. Which I have already done. Still waiting to get the copy of the checks though.
Might call the Staples office of the president today to see if they can help.
