I bought a session of profilho. A day or two before the provider cancelled because of insurance issues. The voucher was marked redeemed, despite that not being the case _ I suspect groupon did this to make it more difficult to get a refund. Grouon asked me to get a confirmation email from the provider saying the service was not provided due to their insurance issues. I provided this email to Groupon in early March. Since then they have failed to respond to my emails asking for the response, which was promised within 7 days. This is not the first time. I was stupid to use them again. There is no customer support, and they do not know the meaning of honesty or customer service. Two months after providing them with what they requested, no refund, no communication. It's not very hard, it's impossible to get a refund - £100 down the drain.
