Thank you for your valued custom which is very important to me. I must, with respect, draw your attention to my cancellation policy regarding missed or cancelled appointments which I kindly ask you to observe.
I understand that appointments sometimes need to be rearranged and you now have access to do this via your login on the website.  This must be done with a minimum of 48 hours notice prior to your appointment and to avoid any charges.   You will not be able to amend your appointment online within the 48 hour period and I ask, in those circumstances, that you contact me as soon as possible.  
Please note that you will be charged 50% of your treatment cost if you cancel between 24 and 48 hours and 100% within 24 hours.  If I am able to refill your appointment, I will credit your account minus any deductions for the treatment cost difference.  If you fail to show up for your appointment, you will incur the full cost of the booking.
My time is precious, I hope you understand.
