Dear Sir or Madam:
Just a quick message to let you know that I much appreciate your employee driver.
I used your services few times and I noticed that he is very nice to clients, an efficient driver and he is clearly appreciated by the border employees, which can make a big difference in certain cases.
He is surely an asset to your company.
I wanted to provide some feedback on booking with you and the service I received.
This was the first time that I had to do a visa run, I found your colleague, the driver extremely professional, friendly and organised. He also ensured that the group took a break. Finally his driving was very safe.
Thank you for the emails with all the information and please pass on thanks and appreciation to the driver - he is a great representative of your organisation.
I would definitely use your services again and recommend you to family and friends.
