Please i need to close my all dhani services. I never used any single rupee from the dhani one freedom card but there is a lot of debited from my Bank account as ecs return charges. I can't afford this . So please cancel all my services from India bulls dhani app. I have sent a lot of mail to the costumer service but they didn't even reply for that.
