Leaving the organisation immediately after the submission of the letter of resignation is an abandonment of the employment. But then you could have been little thoughtful while doing so. You cannot leave or join the organisation at your whims. You could have thought of the conditions of your employment mentioned in the letter of appointment. It was incumbent on you to fulfil those conditions.
Anyway, at this stage, the only solution left is to go back and approach your old employers to sort the matter. There is no other remedy left for you.
