Amul / Gcmmf — 500 Gls butter bad foul smell and fungus

Address:

Ahmedabad, Gujarat

I ve bought 500 GM butter from big bazar in December 2015...when I opened the packet there was black and white spots of fungus on it and foul smell was extremely bad. I called the toll free number and they asked me to wait until ahmedabad office will receive my complaint...I am waiting for one week but no response from amul
