My mum and I had been looking forward to this spa ...

My mum and I had been looking forward to this spa visit for many months. It was a birthday treat and we had been saving points for six months to go and celebrate the special occasion. When we arrived went straight to the swim lanes machines. I had been dying to try these out as I am a keen swimmer, so was excited by this new experience. However when we got to that area it was all closed off. Not only this but the Jacuzzi was as well. We went to reception and they explained that it was all closed for the whole day for maintenance. This was so disappointing to us as it had been one of the main reasons of mine to come specifically to Nirvana.
Looking at the map we saw the only other Jacuzzis were outside. Braving the cold we attempted to find these, only to find these were also all closed due to maintenance.
I understand that work needs to be carried out, however it would have been thoughtful of the Spa to at least either send out an email to customers to notify us of the closure, and give us the option to rebook on another day. Or even let us now upon arrival when we checked in at reception, rather than having to wonder around finding out for ourselves.
There were also other irritating things that happened throughout the day as well. It was extremely busy and so we could not find lockers in the first changing room and had to walk to secondary one with all our bags while in our robes, we could not find beds together around the pool and the costume dryer not working. Unfortunately it made us feel that standards had dropped and made the day not so enjoyable as we had hoped.
My mother was very disappointed and wrote to the spa concerning this. She received a response from the Spa to say sorry for your disappointment however they are not willing to issue any kind of a refund. I understand that some issues cannot be helped in businesses like this but would have hoped for price of the experience and the amount of people there on the day, some sort of understanding and compensation could be offered.
