Rude and treatment aggressive

I bought a voucher from perfect 10 where I am eligible to get 3 treatments. The terms say you must book a week in advance witch I did not have a problem with since I bought it before my Christmas holiday.<br> <br> Then I started to phone :\ sorry we are fully booked"Eventual I asked the lady now when am I going to use this voucher as I must use it before 31/3/15. She rep**** next year you will get a space. I have tried twice this year.\"" Sorry\"" I decided not to mention the voucher when making a booking and voila I got an appointment. I arrived and the moment I showed the voucher they were reluctant There was 3 the******s with one customer.<br> <br> .. they squeezed me in as they thought I was a paying customer! I asked them what was the difference they must some time do me as well. They said they do not get any money for the treatments that they do for this vouchers. I insisted and after many waste of time and phone calls the manager said she would do me"
