I bought kellogg's cornflakes few days back, from 24*7 shop situated at cyber city gurgaon. I thought since its a reputed shop, the quality won't be compromised here. However the cornflakes bought were again rancid.. There is a stale smell in these cornflakes.
Similar issues was faced when i bought cornflakes a month back from my society shop. Please help me. I want to get my money back. I havn't consumed these cornflakes.
