I submitted a receipt for items that coupon.com was giving money back. I didn't use any coupon for these items now for some reason my receipt is a little hard to read one number although the amount I paid for it shows in the balance as I ask this lady name Irene why wasn't I given the cash back she tells me I modified my receipt... REALLY... and she was gonna close my account... So I ask her please show me where I did this... No response from her no response from anyone and I wanna file a complaint against her whomever this person is but of course no number to call... Wow
