About CSB Bank
Phone banking at CSB Bank, the old Catholic Syrian Bank, runs on the toll-free 1800 266 9090 and covers net banking, the CSB Mobile app, UPI, cards, deposits and general account queries. A chargeable line sits beside it on 022 45393950, and [email protected] takes anything you would rather put in writing.
CSB splits its written complaints by channel rather than pooling them, so a net banking problem, a UPI dispute, an ATM or card issue and an unauthorised debit each have their own mailbox. A lost or misused card has a direct blocking line, and digital payment fraud goes to the bank's FRM cell.
CSB also runs country toll-free numbers for callers in Saudi Arabia, Qatar, the UAE and the United States. Keep your account number or customer ID ready before you dial. CSB will not ask for your OTP, PIN, CVV or net banking password on a call, whoever the caller says they are.
