Asian Paints — Ant eating interior wall paints

Sir,
I have used Royal shine emulsion paint of Asian paints brand for my interior bedroom wall, Group of ants destroying the paints day by day, they are eating the paints and making a branch .I am very much dissatisfied with the Asian paints paint quality .they are taking a huge amount of money for this paint but if they can't provide the best quality then why should we trust Asian paints .
