Duel Employment issue

Hi, I joined IT private company A on [deleted] and resigned the job and released on 2-Feb-2021 (4 Days after joining), but due to by mistake I accepted one offer from IT private company B and joined on 1-Feb-2021 till 21-Feb-2022 (Worked more than an year) Now there is a overlapping between company A and B on 1-Feb-2021 one day overlapping. - Company B is saying we can't update joining dates in our database - Company A is also not respondin For this 1 day overlapping issue what would be solution? I have below documents with me Company A Reliving letter and Experience letter, UAN, PF No, 4 days working Salary Slip Company B Reliving letter, PF no, UAN, last 6 months salary slips, after few days I will get Experience letter. Question 1. How to solve this issue if both company is not responding? 2. Is this issue exist and affect my entire career? 3. Is this issue affect at the time of full PF withdraw? 4. What if I don't merge Company A (4 days working) PF in next new jobs?
