Did the management impart you any exclusive training with salary soon after your appointment? Even then they can not ask you to pay the sum for issuing experience certificate when the condition was not put in the offer letter or conveyed to you when you submitted your resignation or while serving the notice period of 3 months. They raise such a demand only when you ask for the unpaid salary. Therefore, It is an act of illegality as well as unethical. Send a legal notice to the management to disburse the unpaid salary along with experience certificate.
