StashFin — regarding higher interest rate and fraud

My name is nevesh sharma. I have taken a personal loan from stashfin with a intermediate person mithlesh yadav
Loan no.- sens[protected]
First of all intermediate registered his no. Instead mine. Secondly he told me that interest will be 11% but actual rate is 36%.
After that he told me that after one emi rate will reduce automatically but not reduced till now. I have paid three emi already. So please register my contact no. I. E. [protected] instead of [protected] which is of mithlesh. And reduce my interest rate to11%. If not possible then tell me how to give money back to stashfin. As i am not so rich that i can pay so much of interest.

Please resolve this problem as soon as possible.
