Byju's — product not cancellation. cheating with customer

Address:

Head office banglore

Hello,
I buy product from byjus and as per policy cancel my product in 15 days its date is 25/2/2020 and today date is 7/5/2020, i am doing mail on regular base and receive call from byjus but they still not cancel my product i have to pay emi. So beware from byjus because they cant refund you after purchase and they told fake is cancel your product in 15 days. Today 80 days but product not cancel and my 80k stuck in byjus. This information for my brother and sister you please dont in trap, if you buy one then you will not cancel product.
