Kohinoor Televideo — price issue

Address:

411030

I have purchase dainkin 1 ton ac from kohinoor electronics tilak rd showroom on 1.10.17
Price was fixed for rs.26 k i have applied for bajaj finance in which i have to pay rs.5200 in cash, remaining are 8 installments of rs 2600 as i existing customer of bajaj they r not going to charge any charges
But while billing kohinoor cashier add rs.567 as processing fee of finance and taken that amt through my credit card
So i request him to cancel my loan and take whole payment through credit card
But he refused the same told me that we were not going to cancel the finance.
Bajaj finance executive is ready to cancel the same but kohinoor executive refused our request and told us that he will give extra 500 discount on our next purchase
Why they forced for finance?

Finance co and kohinoor electronics
Both are connected each other to loot the customers
So beware of kohinoor electronics
