Byju's — return of product from byju's

Address:

Flat 508, Amrutha Hills, Opp. ICICI Bank, LancoHills Road, Amrutha Hills, Hyderabad, Andhra Pradesh, 500089

Though the product is returned and acknowledged by Byjus, They are not processing the refund. They are saying it will take 21 working days to process the refund while their website clearly mentioned that 10 days. They also initiated loan process with Capitalflaot without my consent. Inspite of 3 days after returning the product they have not cancelled the loan. byjus is chor company and their false promise of 15 days is a trap.
Kindly arrange my refund and loan cancellation at the earliest.
