Punjab State Cooperative Milk Producers Federation / Milkfed Verka — Verka milk 1.5 ltr pack sold at higher price in Mohali

Address: Phase 10 Mohali

I purchase the verka 1.5 ltr green pouch today. The vendor - Verka milk shop phase 10 mohali charged INR 77/- instead of the printed INR 73/-
When asked why he charged extra INR 4/- he said it was 2 half ltrs.
This is cheating as the consumer should get the fair price.
Please stop this corrupt practice immediately.
