"Dear Ockert
I'm writing to thank you for your outstanding service.
You were patient, polite, honest and professional. You listened carefully to everything I said and I knew I was in good hands.
Thank you for always being on time and confirming each appointment and instruction, keeping me up to date with developments.
I was also impressed by your attention to detail, adding personal touches, your sense of humour and going the extra mile when the house was on show. I know, if I need expert advice, I can rely on you.
Dealing with you have been a positive experience, and I wish you every success.
Yours sincerely, "
