Hi Shina,
At the outset, let me clarify that this site is designed by a group of senior Banking Professionals to assist Bank Customers at large to provide guidance for resolution of any complain/query/grievance in respect of financial services. This site does not belong to any Bank or a regulator, which may please be noted.
From your complaint it appears that you have not settled your credit card dues for a considerable period of time due to which a small outstanding has swelled into a huge sum. It is important to know that the banker under Indian Contract Act has the right to mark lien on your account for recovery of your dues to them.
A lien is the right to retain all securities of the customer in respect of the general balance due from him (Section 171 of Indian Contract Act). Lien is of two types — particular lien and general lien.
In general lien, the right of retainer is not only for the debt incurred for particular goods, but also for any general balance due. A general lien extends to general balance of accounts (by combining all accounts); extends to prior transaction; to properties/ securities which a banker has come in possession of in ordinary course of business viz cheques deposited for collection.
Your argument that the bank ought not to have marked lien on your salary account with respect to your credit card dues is not tenable. The way out for you in the above circumstances is to arrive at a negotiated settlement with your bank.
In case your branch is unable to sort out the issue you can write to Nodal Officer of your bank for taking a positive view and resolve the issues. It is very unlikely that you will receive any relief by approaching the Banking Ombudsman or other similar forum, unless you have any supporting documentary evidence to establish that your attempts to settle your credit card dues in an amicable manner has been frustrated by your bank.
