Refusal to supply supplier detail for refund.

I ordered an item from Groupon and only realised recently that I had been billed double what I should have been. I contacted Groupon Customer Service and was told by Angelique that my complaint was raised more than 7 days after receiving the order and for that reason they could not help me. I explained the situation again and asked to be given the supplier info so that I can take the matter up with them. This she refused saying that the information was confidential. This notwithstanding the fact that that this exact process is explained in their FAQ.<br> <br> A company that would rather lose my business than provide a acceptable level of service? Also a company that seems to flaunt the Consumer Protection Act. It goes without saying that my Groupon account is now closed.
