Appauling customer service!!!

After waiting two days for Groupon to confirm the account holders details, I paid the monies using the correct reference only to find out a day later that my two vouchers had expired. I contacted customer service regarding getting a refund or having the funds kept on my account for future use but I am STILL waiting for a response!!!!<br> <br> Forget any future purchases, I want my money back!!!<br> <br> Thank you for your absolutely terrible customer service Groupon!
