Subway — wrongly charging customers

Address:

603203

This happened at subway srm university kattankulathur campus. They have menu board saying extra cheese for ₹25 but they charged me 60₹ for extra cheese. After objecting the biller talked to his superiors and told me that prices have been revised and he took off the board menu in front of me after that i paid ₹60 for the extra cheese. When returning next day i can see the old menu board put up again which says extra cheese is ₹25. They charged me more than double the price for extra cheese and they put up the same old sign board again.
