Onida — About bad condition of mother board of my led onida tv within near abaut 7-8month.

I brought new led Onida TV in month of January.but this TV is bad condition from back one month. Mechniq from Onida company came my home and see the status of TV.he say that mother board of your TV is not working properly.I change the mother board within 4-5days.but still he is not coming.then i call Onida Custer care by lodging complaint no.1507A[protected].but still no response is coming from Onida customer care.they simply misguide us by telling server down hai, complaint close kar diya. mother board nahi hai. Thiskind of misguides done from Onida customer care to custmers.
