Dear Mr. / Ms,
I was very concerned when I received your letter of yesterday complaining that the central heating system in your new house had not been completed by the date promised.
On referring to our earlier correspondence,I find that I had mistaken the date for completion. The fault is entirely mine and I deeply regret that it should have occurred.
I realize the inconvenience our oversight must be causing you and will do everything possible to avoid any further delay. I have already given instructions for the work to have priority and the engineers working on the job to be placed on overtime. These arrangements should see the installation completed by next weekend.
Yours faithfully
Dear sir：
Thank you for your letter of 20 September, requesting a reference for Clairish Computers Ltd. The answers to your questions are as follows:
1. We have employed Clairish Computers Ltd. since January 1995.
2. Clairish Computers has helped our company rectify a new computer system that had been badly installed by another firm of consultants. It has drawn up a system specification for a replacement system and has chosen appropriate hardware.
3. We did not select Clairish Computers from several candidates.
4. We were not first time computer users.
5. Our first system is working satisfactorily. The replacement system is still too new to comment on.
6. We are satisfied with the work of Clairish Computers. The various stages were completed on time, and the charges agreed with the quotes.
7. There was continuity of staff at Clairish Computers. Ian Baird managed the work, which was carried out by Alex Johnston and James MacReady.
8. The staff training was effectively carried out.
Yours faithfully,
Peter Haddon, Director
Mr. Wu,
you may already know that the Directors of the company will soon have finished the reorganization of the business and that this will result in a decrease in staff. I am very sorry to inform you that your position is one that will shortly become redundant, and that you services will not continue after the end of this month.
We have no cause of complaint against you, on the contrary, we are quite satisfied with your services during the three years. The reduction of staff is entirely due to business doldrums. You will of course be entitled to a redundancy payment. In your case you will be given one month‘s salary for every year of service with the company. Besides, we shall be pleased to provide any prospective employer with a testimonial of your character and ability.
Please contact me if you have any questions.
