Byju's — Non return on EMI Amount and not stopping the EMI

BYJUS IS A BIG FRAUD COMPANY. NEVER TRUST THEM.
I have returned the product i purchased from Byjus of amount 56000, (Fifty six thousand).
I got it financed from the Bajaj Financial as loan.
Which was processed by BYJUS sales person on my behalf..

As promised I have returned the product. But I am still been deducted for EMI of Rs 4667 per month from last four months.

BYJUS has neither refunded my EMI nor stopped the EMI.
I have totally been deducted by Rs18668/- till date.

They Byjus contact person is not responding. They just have same excuse for extending the dates.
