Canara Bank — Fraud bank to bank with

The worst bank to bank with. They switched my salaried account to a savings account without telling me why, sent me a notice stating that I needed to pay off some debts, and when I called, they said that because I hadn't kept a certain balance, they would charge me a surcharge. As a result, my account went negative and I needed to pay off those debts, but I didn't because earlier, when I remitted a cash payment, they deducted 600 rupees, so i never gonna pay 600 rs again as they have fraud concept within the banking systemI will never pay 600 rupees again because of their idea of banking system fraud. As a result, my credit score has been negatively impacted by their work, and my credit card application was rejected as a result of Canara Bank fraud procedure.
