1300 deducted for health insurance while opening sbi savings account. But the next time debited 1300 rupees again I have not filled any insurance form or signed any document. When I went to the bank, the manager asked me to talk to a private number and said that the refund would come very soon.But it's been more than 6 months and I haven't received a single refund. I have been repeatedly harassed by the bank and the manager has not taken any steps.
