Customer overcharging while purchasing 500 ml Govind toned milk bag

Due to the lockdown in goa, the domain investor decided to purchase milk. The price of Govind toned milk , 500 ml milk bag is less than other brands.
For the packets which were available, the MRP price was not printed properly, only the top part was clearly visible.
The domain investor read the price as Rs 23, yet one of the store staff incorrectly told the price was Rs 25
The young woman said that the price is Rs 23, yet she charged Rs 25
On Swiggy, the price in Pune for Govind toned milk , 500 ml milk bag is listed as Rs 22
So due to the cheating attempt, instead of purchasing two milk bags, the domain investor decided to purchase only one milk bag.
Milk manufacturers should print their MRP clearly to avoid cheating of customers by retailers
