I had participated in social insurance in Thang Long Bridge Construction Joint Stock Company from 2002 to 2007. In 2007, I resigned and the company closed the social insurance book for me until 2007. After that, I moved to Tuan Thinh Construction Company Limited to work from 2009, and until 2016, I reported a decrease, but in fact the Tuan Thinh company only paid the social insurance premium for me until January 2012. So what are the procedures I need if I want to close the book? Sincerely thank you!
