Subway India — overcharging

Address:

403001

I visited subway outlet at campal in panjim goa.
My bill amount was rs. 253.70
I paid my bill using my credit card. The amount charged to my card was rs. 254 instead of the actual rs. 253.70
When questioned, the team didn't have any answer to this.
This outlet maybe doing the same thing with other customers.

This is cheating...
