Axis Bank — deduction without reasons

I had extreme level bad experience from axis Bank, I have a salary based account since 2015 and suddenly without notification convertedd into saving account (ecs) in jan2018, and this month I kept 60000/- then also 900rupee consolidated charges deducted from my account. And again it's showing -588rupee. I asked many times to customer services why is this happening to me so they said consolidated charges and converted account in saving ecs. All time customer services kept quite and at last they said we can't refund you money, sorry sir if it's possible then we can do transfer your money back but we can't so close your account and again open zero balance account. But what should I do with my negative balance and i lost my 4200rupee. Axis Bank means horrible experience.
