Address:

B.R.M.B ROAD ISMILE ASANSOL NEAR SOPEN KALI MANDIR, Burdwan, West Bengal, 713301

Frequently money is being deducted from my account from past 2 months
A total amount of R.s 2700 (Approx) is being deducted without any reason .

Any proper reason is not being displayed by the bank.
When we add money to our savings account, a certain amount of R.s 280, 270 and many more gets deducted.

I will be highly grateful to the authority if this refund is being done.
