Dear Sir / Madam,
I would like to express my gratitude to your company and, particularly, to your colleague Тhea who was very kind and efficient in helping me solve my problem. Owing to Thea’s best efforts we managed to correct a mistake I had made by accident, which could have made me a big problem later.
It would be great if all companies would have such employees – willing to go an extra mile to assist the clients, and to improve their company’s rating by their full dedication at work.
One more time, Thea, thank you very much for showing your willingness and commitment to help me. That’s the right way to do business!
