THANK YOU TO SATISFIED CUSTOMER
On behalf of our Company, I would like to thank you for your compliments. We pride ourselves on giving our customers the very best, no matter the magnitude of the occasion.
In response to your kindness, we thought it would be fitting to send you a gift certificate that is but a small token of our appreciation toward customers such as yourself.
Sincerely,
GOOD CUSTOMER SERVICE
I wish to thank you and your staff for providing such excellent service. It was a pleasure to deal with members of your staff. The service was impeccable, and the staff was always very well-mannered and helpful. I was truly impressed with the level of dedication present.
This is not the usual letter that I have the pleasure of sending out, since it is not every day that one comes across service of such a high standard.
