Vasanth & Co — Onida led tv 55 inch

I brought onida led 55inch tv on 20th march 2017 and its installation done on 26th march 2017. Since it is new home our house warming is on 14th april. After that only we started using it. From 15th april the tv is automatically getting on and off. I complaint to onida customer care on 18th still now it is not rectified they are saying its dealer mistake. When i check with vasanth & co they are saying they will come and rectify today. Im daily taking leave and waiting for the technician. No use. My hamble please dont buy any thing in vasath & co. Once they sell to us they wash there hands.
