Byju's — Loan cancellation Pending

I Ashutosh Dwivedi had bought a UPSC IAS course through byjus but in 12 days i got that the course was not what i was looking for my optional so i cancelled it and got the refcund and requested for my loan cancellation also but still it is pending with them for 8 months and no one is replying to me on that, because of which my CIBIL score has depreciated 130 points.
