Faber — chimney repair (issue with chimney within one year)

Despite repeated calls, our complaint still sits with faber india (Complaint originally raised on 22 july 2020). My mobile number is [protected] and both rajat, ramu prasad (Asst service manager of delhi ncr) have stopped receiving my calls and have no answer as to why my chimney motor (Which got repaired within one year of purchase) is still not replaced. Worst experience with faber, i thought faber was a global brand but my bad! Please help in getting this fixed at the earliest.
