You recently bought a new piece of equipment for your home but it did not work.
You phoned the store but still no action has been taken.
Write a letter to the store manager. In your letter:
- describe what equipment you bought
- explain the problem with the new equipment
- say what you would like the manager to do
Dear Sir or Madam,
The purpose of this letter is to express my dissatisfaction with a purchase from your store last week.
The device I purchased is a Sanyo Deluxe blender, model SDB-2000. It is one of your top of the line blenders and it cost $89. I bought a silver one, with black trim.
The main problem is that the blades do not spin properly. At first, everything seemed to work fine but within a day the blender started to shake uncontrollably. At the same time, there is a strange knocking noise and I can see the blades wobbling. I immediately called the shop for assistance; however, despite promises to do so, no one has got back to me.
I would appreciate it if you could replace the faulty blender with a new one under the one-year warranty. I have retained the purchase receipt.
Please contact me and let me know how you intend to resolve this matter.
Yours faithfully,
Sarah Smith
