A person worked in a company for 7 years. When he left the company and tried to transfer his PF balance to his current company, he found that his previous company had neither added his joining date nor his leaving date. Despite requesting many times for his previous employer to add the joining date, they did not take any action. The person has his joining letter from the company. Now, please suggest how he can add his D.O.J. to the portal without the employer's involvement. Is it acceptable to submit a joint declaration supported by the joining letter?
