You recently had your computer fixed at a local computer store, however, you are not pleased with the service you received. v.5

Dear Sir or Madam, I am a regular customer of your store and have found all my interactions with your office very satisfactory. But, I am sorry to say that the service I received last week, to have my personal computer repaired, was not as per your excellence. I am hoping that you would rectify the issue to keep your reputation intact. First of all, the front desk technician was not available at the time of our prescheduled appointment. I had to wait 45 minutes for him to appear. However, this was just the beginning of the poor service I experience yesterday. He did not seem to have enough understanding of the computer hardware and Linux operating system and it took me 30 minutes to explain the problem and then he accepted my computer for the warranty. On 19th November, when I collected my computer, I noticed that the invoice includes the cost of the keypad replacement! I never lodged a request to change the keyboard! I request you to look into this matter and remove the keyboard replacement charge from the invoice. Also, appoint technically sound personnel to your service team as they represent your company. I am looking forward to hearing from you soon. Yours faithfully, Ramanuj Sharma
