Tasmac — took extra money for more than mrp

Address:

600056

I took 1 750ml royal challenge which costs 720 and 1 375ml signatures which costs 360. But the shopkeeper took 1200 for both. When i asked mrp is less but refused telling everywhere it is like that and demanded money and took from me. Please make sure this should not happen to any other citizen. Take necessary action based on this complaint.

Thank you.
