Full refund on voucher

We bought 2 Groupon vouchers for a 90 minute full body and hot stone massage at a certain massage centre as a treat for us seeing as we do not see each other that often. We specifically booked the massage for 2 (myself and my sister) almost two weeks in advance. When we arrived at the centre, there was a very upset customer. Apparently the centre did not accept her voucher, after she also booked an appointment in advance, and there was only one the****** on site (we will still get back to this point.) She eventually left the centre. The Lady behind the desk said, there is only one the******, so I will be massaged first and then my sister. In other words, they made three bookings on the same day and time with only one the******. This was not acceptable seeing as we have already made other plans for the afternoon and could not stick around another 90 minutes due to their error. When trying to explain this to the lady, she could hardly understand one word and we ended up with no massage and loosing our money.<br> <br> Groupon refunded us with vouchers even though there was no fault on Groupon's side! The service we received from Groupon was outstanding, professional and quick! Great service!
