Subject: Unsatisfactory Annual Maintenance Service for Samsung ACs

Dear Sir

We had taken an AMC (Annual Maintenance Contract) for our 16 Samsung air conditioners with your agency under contract to AMC 23/17 on 15th March, 20xx. At that time, we were assured by your Marketing Executive that your service engineer would carry out a monthly preventive maintenance visit in the first week of every month and any other complaints registered by us will be promptly attended to within one day.

Unfortunately, the preventive maintenance monthly visit for May has not been held so far. Last month two of our complaints got an unsatisfactory response from your side, as they were attended after 4-5 days. This is causing great inconvenience to us. Our students have started complaining and threatening to boycott classes due to the discomfort during summer.

You are requested to initiate action at the earliest so that you honour the terms of the AMC, otherwise, we will be compelled to go to the consumer forum for redressal.

Yours faithfully
Dev Arora

Subject: Damage Caused to Monument


I wish to bring to your notice the deplorable condition of the Victoria Memorial Monument and the grounds surrounding it. Being old, the monument is in constant need of repairs, which are not being carried out periodically or when required. This should be arranged by your office, as the Government of India has authorised you for this purpose.

Further, the grounds are littered with soft drink plastic bottles, paper scraps and polythene bags thrown by visitors, much to the disgust of foreign tourists. This monument is of prime importance to the history of our country and it is about time the civic authorities should realise this fact. They should carry out the cleaning regularly.

Necessary repairs should be carried out to the interior as well as exteriors of the monument. Security personnel should be increased to prevent littering of the grounds. If these measures are carried out, I am sure the Victorian Memorial will regain its lost glory.

Yours faithfully
Reena Basal
