Hi,
I wrote to my local MP and Staples head office as i was so angry with these conmen praying on us at every opportunity, my MP wrote to AS-Securi-T Ltd. and that was the end of it, Staples never did reply, we won't ever shop there again.
There is some great advice on this site on how to deal with these jerks.
Good Luck and may the force be with you....!
