Complaint Review: Groupon

I order tickets for Fair  Park Winter  Wonderland..  Groupon sent me an email showing  the charge was $100 but when  I check with my bank they charges me $200 and sent tow sets of tickets.  I cancel  both sets ot  tickets within in  10 minutes of the order.  I tried calling an 800 number I found and  it  was  just a recording stating  to file  a cancellation on their web site.  I  did this twice and request a call back.  This was on  Decembrer 8.  On Monday, December 11 I placed three request for the tickets  to be cancel and give me a refund.  I then went on Facebook andPM them.  I received an email stating they would not refund my money because I did not cancel  on Friday. I sent  two request on Friday.  I finally got  them to call me, they placed me on hold  and  then the call was disconnect after 10 minutes  of me waiting on line.  This company is a ripoff.
