Mother Dairy — complaint regarding sour rasmalai

Address:

New Police Lines, Kingsway Camp, Delhi-110009

2 days back i brought a pack of rasmalai from mother dairy near my home, it was sour in taste, i informed the retailer he asked me to complaint and gave me a new pack. I consumed 2 pieces of the sour rasmalai, i am worried if it can cause any potential health problem. I tried mailing you but i got a revert to contact directly, that's when i tried calling your executive and no one answered. As a consumer i have some rights and as a producer you have duty of care towards all your customers. No one replied or called me back, is this how you treat your customers? What should i do now?
