Send your complaint to email@example.com. My new Bolan had a faulty meter and was able to get it replaced, by writing to them.
If you are living in Punjab, then you can also approach the consumer courts. But prior to doing so, you need to serve a 14-day written notice to the seller with your complaint and mention in it your intention on taking the matter to the consumer court if it is not resolved. After 14 days you can submit your complaint in the consumer court.
