Maggi — Price charged above MRP by saying production is affected due to covid pandemic.

4 days ago I bought 2 packets of maggi of ₹5 each which he sold me at ₹6 each saying due covid pandemic production is adversely affected that's why they are selling at price higher than MRP. One month ago also I bought maggi, shopkeeper sold ₹5 at ₹6 giving the same reason. If there is such issue why it's not printed on packet and if not then why shopkeepers are selling your product at higher rate?
