StashFin — unrightfully asking for more money

Address:	Kotla Mubarakpur delhi, New Delhi, Delhi, 201010
Website:	www.stashfin.com

My stashfin emi of 10822/- gets auto-debitd from my account every month but they reported to cibil that i have not paid 3 of my emis and also they never answer calls. All their mailboxes are obsolete and i cannot reach out to them through any means. Their exutives keep calling me everyday asking me to pay an amount of 6918/- manually through their app. I tod them that the emi has already been autodebited to whichthey say that they will send me an mail id on which i need to sen y bank statement relecting the same but they send me no such sms.
Please resolve my query, they are really harassing me.
