[Resolved]  Urban Company — Wrongly quoted and charged for Painting services and poor quality

I am quoted Rs: 2, 09, 944/- with 25% discount final is Rs. 1, 57, 683/-, for fresh painting, one coat putty, one court primer, sanding if required and 2 coats of paint for entire house, interior and exterior. With below sq ft type of paint.

Interior:
Ceiling Asian Tractor total carpet area of 1480 sq ft
Walls Asian Royals Emulsion total carpet area of 2715 sq ft

Exteriors:
Walls Asian Ultima 1885 sq ft

Grills enamel 240 sq ft.

However, so far 85% of interior painting is done with only one 20ltrs each of Royale and Tractor emulsion paints.

My complaint is that I am wrongly quoted and charged, on carpet area size and also for fresh paint, when it is only re painting requiring less amounts of putty, primer, and coats of paints. I am seeking refund for being wrongly quoted and charged.
