Termination after resignation from a bank for not serving notice period

I was working with a reputed bank as a deputy manager.I had resigned from there through system but they have given me termination letter for not serving one month notice period even I was ready to pay the recovery amount. i had worked there for 8 month. Now I just wanted to know is it right?? And now I want my relieving letter. What should I do??

Dear Vaibhav,
The Bank must be a private sector bank that too came into existence during the era of LPG. What is pertinent is whether your resignation was accepted subject to the condition of actually serving the notice period of one month. If so whether you obliged or simply walked out under the impression that you could pay it later if so demanded?
Any way, the Bank should not have simply terminated your services in violation of the contract of employment. Send a legal notice to the Bank.
