Hi

Your previous employer, the bank has violated is on terms of bond after taking money from you and then not issuing a relieving letter

Send them a legal notice demanding the relieving letter asking to issue the relieving letter immediately

If the PNB does not require the same then forget this issue.

Yours is a new job and thence there is no likelihood that the PSB would require in it future anymore.

However you can carry on communications with your previous employer to get the relieving letter if in future it is ever required.

You Can think of sending legal notice also to get the same.

The bank will not consider the experience of the employment with the private organisation.

Moreover you have been recruited under the open competitive examinations observing all necessary formalities and rules of recruitment, therefore this appointment is not based on the experience or a NOC from the previous organisation.

Hence you may not be bothered about procuring relieving letter from the previous employer so urgently.

You can issue a legal notice to the previous employer to send you the relieving letter and settle your dues if any, in your F&F settlement, but you should not carry this to your head while joining the new assignment/employment.
