Indiabulls Consumer Finance Limited — Unnecessary subscription fees

Sir,
I have sent so many mails to respective company (Dhani loans and service LTD. Formerly Indiabulls consumer finance limited) for close my account but they did nothing.I took 249 rupees as loan and they took 598 rupees from me still they are asking for money in the name of subscription fees.I got NOC also but still they are sending messages for dues.Why should I pay the subscription money if I am not using it and after paid the loan amount? They are increasing my dues and sending me messages.Actually I have cleared the loan and got NOC but their customer support asking for subscription fees.Sir, please do something I am uploading some screenshots and My NOC.In their advertisement they said no interest, zero interest but actually they are taking so many amounts.Please do something and solve my issue.I have sent them so many mails but they did nothing
