Axis Bank, India — problems with credit card

I am using a credit card with axis bank. It is approaching expiry, but without issuing a new card, they deactivated my existing card without any prior notice (Or) sms.

When i contacted their customer service, they are saying we are not responsible for this and it's entirely up to the sole discretion of bank.

When i contacted my service branch, they are also not taking any responsibilities on this issues.

It is really a bad service (Even worst services) from axis bank india.
