And I like to thank you for your support over the past twenty years. I have enjoyed working at ABC engineering on your project. It was a wonderful challenge to me to help you in your projects. If you have any queries or if you wish to keep in touch with me, I will be available to you on my phone and also at mail. My number is 589647 and email id is email@example.com. I wish you a wonderful future and great success in your business.
