I have been contacting groupon but the customer service number kept saying it is closed. I was cancelling my purchase for overnight stay at Secret hotel in Washington for June *nd since Thursday due to emergency situation at my job that we cannot go anymore. The conversation in our chat with the representative told me to wait for the email but I did not get one, one of the representative said it is still in the que so I have to wait. I called the hotel and they said Groupon cancelled already. I just want to request if even for one time courtesy for a refund or even a groupon credit for the refund of this purchase. It never happened to me before that I cancelled a purchase for stay at the last minute, I hope groupon will consider my request for refund or credit or even another reservation to the same place on another date.**Thank you for your assistance and hoping for your consideration.**You can reach me at *****@***.com
