Hi, I've been working for a startup from past 1 year and I resigned from it last month, served the notice and after the last day of my duty all of my accounts were disabled. I tried contacting my manager, initially I was told that it's going to take few days to provide reliving/service letter but later I was straight up denied citing that my performance was not satisfactory and I'm not eligible for any proof of employment. During my term I was given 20 percent hike on my salary within 1 year, so I don't think the performance thing holds very well. What could be the remedy?
