Dear Sir,

I’m writing to complain about the service offered by your company.

I told your service department on November 21 that my washing machine needed repairing, Your service engineers have since been here four times—on December 1l, December 19, December 25 and January 5．The problem was found out on the first visit and the wrong parts were brought by different engineers on the two next visits.The correct part was fitted by the first engineer on the fourth visit.

In short, my complaints are:

a．I had to wait three weeks for an engineer to call and nearly two months for the machine to be repaired.

b．The engineers who called on December 19 and December 25 had been given wrong information by the company, which made me take two half days off unnecessarily.

c．The first and fourth visits lasted a total of thirty minutes.But in the invoice （发票）, I have to pay for four visits of four hours’ work.I will not be paying the invoice for their mistakes and I do hope to receive your answers to these complaints.

Yours,

Robert White
