Dear Ms. Write, The purpose of t

Dear Ms. Write, The purpose of this letter is to convey to you my sincere apologies for any inconvenience you may have experience last month with respect to the installation(安装) of your Internet high speed service. I just returned from vacation this week and found your file in my in-basket. As soon as I reviewed your case it was clear that somehow your May. 20th request for a change in service had somehow slipped through the cracks. The only possible explanation I can give is that we have recently had a number of key staff changes, which might have resulted in your letter being overlooked. Consequently, I have directed our installation group to contact you by the end of this week to set up time convenient to you when they could go to your house and install your new router(路由器）and make the necessary adjustments to your software. Because of this serious oversight, and as a testament to our appreciation of you as customer, we are going to provide you with your first three months of high speed service for free charge. There fore, your account will not be billed until June of this year. Ms. White, let me assure you that what happened in your case is not typical of CableNet's level of customer service. We continue to committed to providing you and all of our customers with the highest standards of service in the industry. If you have any questions please don't hesitate to call me at 754-978-532. Sincerely, Paulo Davies Manager Customer Solutions
