Bigbasket.com — Bigbasket cancelled my order having discounted items after making me wait for 3 days

Bigbasket has started a dirty game where they are giving sudden huge discounts so that you buy the goods and then cancel them after 2-3 days. Once the order is cancelled the paid amount is not refunded to the original payment source, rather gets credited in BB wallet forcing you to spend only on bigbasket platform. This is nothing but a huge scam these people are doing!
