State Bank Of India [SBI] — Refund not received from purplle.com to my state bank of india account

My name is kavya and i had ordered sunscreens of rs 442 of lotus herbals in purplle.com on 9th february 2021 and paid the amount through upi payment. After that i cancelled the product on 10th february 2021 due to some reasons. Purplle.com initiated the amount but i didn't get the money. Purplle sent this reference number ([protected])and told me to charge dispute form from the bank.So please kindly respond to the complaint its very urgent
