Can my bank freeze my account for unpaid taxes without warning in Hyderabad?

I’m feeling really anxious. My bank in Hyderabad froze my account suddenly, claiming I have unpaid taxes amounting to ₹25,000. I wasn’t even aware of any dues. They didn’t give me much warning and now I can’t access my money. This feels so unfair. Is it legal for them to do this? What can I do to unfreeze my account?
