Asian Paints — Code color mis match

Address:

EF 7/109, KSHB FLATS, CHEVARAMBALAM

Dear sir i had painted my flat with asian paint 2 days back, i had painted 3 bedroom with one color and other two room with another color.
usually i had color code 0315 of ace ivory before so without changing the color is brought 4 litre of 0315 ivory color so that i could finish it with one coat. my painter painted the room but after some time we found that the code shade was different and it looks like off white, so the color is looking different, and at the same time i had painted the room with code 7928 with 4 litre, this code is also having slight difference, This has made me mentally difficult and i complaint with the shop where i had purchsed the paint from COLOR STUDIO, CHEVARAMBALAM, they came to see my room and told to complaint to asian paints., Actually because of this problem i had to spend more money for my labour charges for painting
Sir plz solve my problem, as soon as possible
