‘Dear Mr Kotecha,
I am writing to inform you I will no longer be attending your dental practice as I have been re-located with work at short notice and so travelling to the surgery would now be unpractical.
I would like to say however, I have found your practice extremely helpful, friendly and without sounding too cheesy you’ve made dentists appointments a lot more bearable.
Again I would like to thank you for your services’
Yours faithfully
Mrs. CT, New Duston, Northampton
