Nobroker — Home interiors

I have engaged no broker for home interiors. They have shared one quotation based on my requirement.
But at the time of final quotation they totally changed the same and include exorbitant charges. Item included is way higher from market price. They are telling scope has been increased but scope not increased much.

They have cheated me.
I request to return my initial amount of Rs 22500 which I have paid.
