Groupon Groupon ripped me off Chicago, Illinois

In August 2010, Groupon offered a discount coupon to a Tattoo shop. I
bought 4 of the coupons at $49 each.  Groupon offers a refund policy. 
So the next day I changed my mind on the tattoo and requested a refund
for all 4 Groupons.

They refunded me for only 3 of them... ripping me off for $49.

I emailed and called every day and they kept saying they refunded all 4 of them, and then blamed it on my bank.

To this day, I have my bank statement where it shows I was only refunded for 3 of the $49 charges. Not all 4 of them.

Prior to this happening, I used Groupon very often. However, since this incident I have not used them since, not once.

No one there would listen to me, they were very argumentative, and no one would give me the refund that I am owed.

They owe me $49.
