Micromax — tv issue

Address:

500045

I have brought a tv on feb 2018 and i could see a thin line on tv. Over this issue i tried connecting to micromax customer care care through different number but could not able to. I have a year warranty+ 2 year of extended warranty. Please advise me over this issue. Also it is really surprises me that there is not even a single customer care number by which i a can get in touch with.
