Sbi life not giving back money
So my father went to SBI to do a pension scheme. Some bank employee told us about retire smart plus. We first thought to invest in that and did some initial paper work, video verification we didn't do. After coming from the bank, I researched about it a lot and decided not to do the insurance. We informed the bank. They told us if the money got deducted, it'd be refunded. Our 3 lakhs were deducted. It's been 15 days, we didn't get the refund. We don't even have any policy number, just has a proposal number. I emailed sbi life, bank manager etc but nothing is happening. What to do? Please tell me.
