Address:

we want to replace our ac as soon as possible. we purchased ac on 18/03/2012 from raj reef canteent but they make us fool, they charged rs 1500 for installation in the name of LG company, but they sent their own technician to install.after 20 days ac have many faults, we call the lg customer care for service but they refuse to check it they said that dealer will have the responsibility. after that we call the dealer ;after so many calls and requests they sent their technicians to repair that they top up the gas assure ac to be ok. but after 20 days again ac have fault there is no cooling, we again call lg customer care but they again refuse to check it and asked to follow the dealer. after that we made so many calls to dealer but they are not even our calls. after that we also went to LG regd. office where mr. imran assure us, he himself call dealer and ask dealer to repair that. dealer repair that fulfill the gas. but after 1 month we face same problem.3times gas filling in just 4 months. if any problem happen in futurethen who willbe responsible???
