The following is an email sent to a manufacturer’s customer service department on July 20.
Dear Sir or Madam:
We’ve been struggling to solve problems with your product. On June 15, we bought a brand-new refrigerator #XXXAAA made in May and a five-year extended warranty for the product from your online store.
①When delivered the next day, the refrigerator didn’t seem to have any problems, so we were absolutely happy to have it for the first few days. Then the fridge suddenly stopped cooling our groceries. We called your customer service hot line to find out what was the matter. Instead of giving us advice, the hot line representative told us that it was to be ②（ replace ） soon. He kept his word, and another new refrigerator of exactly the same type arrived on June 22.
③But （ been / seems / this / a defect / refrigerator / there / to / in / have） too. This one has ④a problem with the freezer, which began as soon as it was turned on. The temperature stays below zero for a while, then goes up to over 40 degrees for several hours, and back down below zero. As a result, the frozen food in the freezer melts and refreezes repeatedly. We’ve tried to have your technicians
⑤（ repair ） it several times with no apparent improvement in its performance. This has already cost us a great deal in spoiled food and wasted time and⑥（ to / made / decide / repairing / keep / it / us / not ）. To be frank, we wish to return the refrigerator at your expense and receive a refund. We look forward to your instructions on how you would like us to carry out this.
Best regards, Jennifer Thompson
