Will KIIT refund my 65K (after counselling and taking a seat) If I don’t wanna take admission?

No. That fee is not refundable. That fees is refundable on the time of counselling but not after that, refund provision is entertained.
It is clearly mentioned before the time of counselling.
However, you can go and have a talk at Koel campus regarding fees refund issue, if it is acceptable this year. It was not accepted years before.
