Inconsiderate Management &service

We came for our annual strat session for 3 days and booked a Spa for team-building on the last day. Then mixed up the time, thinking it's 12:30, only to find that it was 11:30. We were told that we can't get full body any more but only 30 minutes treatment. No other option even when trying to negotiate with the manager to give vouchers so that we can come at another time, she was just so cold. It is understandable that you can't shift times because of other clients but I'm sure there are other alternatives even if you can give some complementary products to make up for the money paid. Was it another race, she could have made a plan but as always, would never go an extra mile for darkness. The the******s at this place are one of the best but the management is just so inconsiderate shame. We are regular clients at this place and now you lost clients permanently plus we will tell other colleagues at our institution about our experience. Never again
