Mswipe Technologies — fraud charges in my bank account without informing or without my consent

I am mswipe since nov 2019, i am really not satisfied with their service and network since day one. After selling the machine nobody will come visit ur place for machine condition and it's usage. So in the month of march i raised a complaint to close my acct they said since it is charged for march i can continue using that for march and it will be closed in april. But they charged me for apr and may when there is no business due to corona lockdown. Even they try to debit my zero balance acct for eight times between apr and may thru ecs, hence it is a zero bal acct, it got nil bal /ecs bouncing charges from bank side which accumulated to - 4037 as of june 1 2020. They r frauds, expecting blood from their customers. I am. Suggesting and will suggest everyone in future no to do any transaction with mswipe.
