Highly annoyed and baffled

I purchased a necklace for my boyfriend from Markham for his birthday last month. He unfortunately wasn't so keen on my choice so I went to exchange it today. <br> I had previously read the back of my receipt to what the policy and conditions were, to see if they would refund it. It required the item to be returned within 30 days, have receipt, be in original packaging, with price still on, and said they wouldn't refund \underwear
