Online booking for 2 people for a massage. On site...

Online booking for 2 people for a massage. On site we were lucky that we were allowed into the thermal bath as a day guest. You would also have to reserve the entrance, it said. None of this was on the homepage. And who books a massage without admission?
The next surprise when you register for the massage. The booking was made for one person only. Although you get a confirmation for 2 people. Statement from the staff: Yes, it doesn't always work. We know this. The people then ask again by email "
Why, I ask myself, do I have to ask if I have received confirmation for 2 people? And why don't they change the booking platform when they know it?
The staff in the catering area are happy to leave the empty plates for 5-10 minutes. Although the restaurant was not full, and he waited several times past the table. I expect more from the prices.
There are no water dispensers in the spa area. These are now common in many other spas.
