Menawhile am keep on asking to change my due date... already i asked so many times to change my emi due date but my bajaja auto finance agent is telling that i should go directly to the headoffice to change my due date... what is the problem in changing due date as per customer wish. i hate bajaj finserv worst service, ... kindly please save me from this... i went into depression about this. Without my knowledge my bank debiting the money as ACH RTN charge but i already paid the due amount through bajajfinanace.com/quickpay.
