Dear Mr.Alvarez,

I purchased a flat-screen television from Belton Appliances
that developed a defect a month after its warranty expired.

The volume became so quiet that it was difficult to hear anything
When I telephoned your service department to tell them I was having trouble with the sound. the associate,従業員 Jill, informed me that several other people also complained about the problem.She scheduled a repair for the following day. In fact, the technician arrived a little earlier than the appointed time.He fixd the problem in less than one hour and did not charge me for the repair.I am writing to let you know that I have told all m friends about the excellent service from your company
