"Dear Mr Fraser,
I just wanted to pass on my thanks to you for the fantastic service I have experienced over the past two or three months from your company. I have been refurbishing a house that has required quite a lot of new light fittings.
The main reason for this email is to bring to your attention the fantastic customer service I have experienced. One of your staff called Kristina has dealt with my numerous queries, assisted with my orders and dealt with all problems as they have arisen. She has been thoroughly professional, always cheerful, always kept me informed of progress, and has been an absolute pleasure to deal with.
I hope you have some sort of staff customer service recognition system at your company as in my view she certainly deserves it.
I will certainly recommend you to anyone I know that needs to order any lighting.
Thank you again."
