Micromax — micromax led uhd 42"

I registered the complaint to micromax customer care regarding my Micromax LED UHD 42", Ticket No. (JNK[protected]) on 2nd july 2019 and technician called me on 8th july and asked to transfer 6500 to his account then only he will visit to my place. and when i called to customer care, they told me that your complaint has been closed as technician was unable to reach out to your mobile. Even though when i appraised customer care about this conduct of technician they said that we'll arrange the call back to you from senior but till today (12th july 2019) i didn't receive any call from micromax. Let's Boycott micromax, i never experienced such worst service earlier by any brand.
