I am having two different credit cards and each cards having own credit limit. For last few days my credit card transaction are getting declined continuously and i noticed that the limits on the cards reflects in negative balance. I contacted the customer support and the executive informed that the limits were merged on both my cards" This was done without giving any prior intimation at all. While i ask for the prior intimation they informed the bank have full discretion to make any changes without informing the customer" I ask the executive to register a compliant a regarding the same and they keep refusing to register a compliant. Merging of the credit limit without any prior notice leaving me completely stuck with how to make the payment!
