State Bank Of India [SBI] — ECS/ACH charges

Address:

SBI Gagarigol, Bageshwar (Uttarakhand)

I'm using Black app(backed by Clear Tax) for investment in Mutual funds. My SBI account is associated with the Black app for mandate account for future transition and investment. Due to financial issues, I was not able to pay few installments for my SIP so SBI charges 4019.16 from July to Sep month. In July month 2360 rupee get deducted and complain regarding the same on local branch SBI Gargrigol- Bageshwer(Uttarakhand) they suggested to block there card and account too. Also, Black app is also not allowing you to remove the mandated account from the app till you will not enter any new bank account. If I have no other account then what should a customer do. Please help me to refund the amount of ECS/ACH charged by SBI bliendly.
