no service since 23 days post 2500/- paid

I received worst(world) class service from videocon on 1st oct, 2018. My freeze was noisy and not cooling from few days. I kept calling local videocon customer care at 8296068531 for whole day long, finally 2 technicians came and spent appx. 30 mins and charged me 2500/-. They suggested me to install 1 stabilizer to fix issue. I did that on the very next day by spending 1000+ Rs.

The worst and pathetic scenes are as below:

1. Freeze is in same noise mode
2. That bloody fat fellow customer care fellow responds very harshly and illiterately always whenever I called him
3. Technicians no comes switched off from 1st oct onwards ( 9916269775)
4. That black fat fellow customer care fellow does not have any records of technicians visited my home on 1st oct. 18
5. That bloody black fat fellow customer care fellow is a non sense, dumb, worst man kind, waste human being.

I called him many a times but no resolution received yet.

Please help me ASAP.

Thanks
Bikram
