Urgent cancellation due to bad service

I recently signed up with gym company and on the day of signing the staff was excellent until I wanted to try the facilities. The staff at the spa was extremely rude they told me that I need to book in advance and that they can’t do anything to help because they were fully booked but on their sign in sheets there was barely bookings for that day. This was while bringing a guest to join too. My guest was surprised at this service and when I complained the ladies said they will give us a time slot (suddenly there was availability) ... second incident I forgot my tag at home as I did not expect to go to gym and I didn’t have access. This is no way to treat clients! I really want to cancel this **** gym and go back to virgin active.
