Kaff Appliances India — KAFF Filterless Chimney oil dripping on the gas stove

Bought KAFF Rover DHC 60 Filterless Chimney on 8-Dec-2021.
After auto clean oil is not collecting in oil collector. Rather than it is dripping outside from motor housing and it falls either on the mesh cover or directly on the stove.

Waited for nearly 2 months to see if this works, but didn't worked at all.
Technician visited and he said nothing can be done and this product works like that.

I have already used Faber in my other houses but never got such issue.

HUGE mistake by trusting KAFF. I am looking to get the product RETURN and REFUND the amount.
