Dear Sir or Madame,
I am writing to complain about the low quality of your customer service.
One week ago I purchased a novel microwave oven in your store. The equipment was delivered on time and the package had no signs of damage; however, when I tried to use it, the oven won’t work. I immediately phoned the shop.
My phone call was answered by a representative of your firm who initially implied that I did not use the equipment properly and that, perhaps, reading manual may help. After I described in details the problem and my actions, he agreed that the oven is out of order and promised to send a specialist in microwaves who has never shown up.
Now, I demand that this malfunctioning piece of equipment was replaced by a brand new one. The new oven ought to be delivered within a week. If my requirements are not met, I will request a full refund as well as a complaint on you will be written.
I am waiting for your prompt response,
Sincerely yours,
Eugene Dubinchuk.
