Faber — bad service

I had purchased a faber chimney in the month of february and it worked well till june but all of a sudden it stopped working and when we called the service executive he said that there was some problem in the circuit and that it would not be covered in the 12 year warranty because we hadn't purchased an additional amc (Annual maintenance contract) at the time of our purchase and we were going to have to pay for it. When we called the helpline they said they couldn't do anything and surprisingly asked us to pay the price for the amc. The most unprofessional part was that no mention of this amc was made at the time of the purchase. I humbly request the company executives to develop the basic courtesy to assist the customer when he/she calls. If no action is taken from faber's side then i have no choice but to take action on the company. Sorry for being rude but it has been almost 5 months and i can't keep a dummy chimney forever.
