Dear sir/ madam

Reimburse the amount immediately.

In the month of august my account was deducted for an amount of 510 rupees for a reason of min balance and in again september they have deducted 710 for the same reason.
Why this hell it happened. Every month till now you pupil used to deduct 126 rupees only.
Its shame on hdfc back to deduct amount like this with out prior intimation.
