how pleased we have been with your service
Nowadays, people do not take the time to sit and write letters unless they have something to complain about, but this is certainly not a letter of complaint. When in business, it is most imperative that technical problems are dealt with as soon as possible as the computer is the central part of any company. I would like to express how pleased we have been with your service. You always act so promptly and efficiently to any calls for help we make. Many thanks for all your help.
