Did not Receive What I Paid for - Very Upset Customer

I decided to get the Personal Trainer Starter Pack - 6 Sessions. The first session i was told was a consultation. My first session, i was told to do the treadmill, stepping machine, and join an ABS class. My second session was booked with a personal trainer, she asked me to do the fitness flyer, then we did ab excercises, and finally the treadmill. The following day ( Thursday)i was unable to go to gym as i had to work late. I let the personal trainer know by sms. I heard nothing from her Friday, Sat, Sun, or Monday. Tuesday i went into the gym to talk to the Manager Tumi, I explained the problem, no one seemed to want to train me for the 4 remaining sessions i had purchased. I Asked for a refund, but he said no he will sort it out, by 10 o clock the following day. Wednesday nothing happened, i went into the gym at about 3:40, was told the manager Tumi was working out but i could go and talk to him. I approached him, and I was very upset as nothing had been done. He got so angry with me, he said I was interrupting his workout, (i was told to go speak to him). He called his head of personal trainers, and shouted at that person, then called the personal trainer, and told her to sort it out. I was shocked that he did all this in front of me. I left the gym, called the Virgin Call Centre to report this incident. Went to my car and cried my eyes out. A While later someone called me, she was totally unhelpful, and said she would look into it and get back to me. i am still waiting. Honestly why would they get back to me? They have my money. If i don't go back to that gym it will be no loss.
