Writ of Mandamus is pending since 3 years from 2015 onwards

I was appointed in a Central PSU and after serving for 10 months out of 1 year of probation, the company has terminated my services abruptly without any prior notice or without giving any opportunity to me. I have filed a Writ of Mandamus in the High Court A.P. and Telangana in July 2015. Company has terminated two others along with me on the same day and referring same clauses. They also filed separate Writ Petitions. The High Court has given the Judgement in favour of one of them in Jan 2016. My case and my other colleagues cases are not getting listed since Jan 2017. Company has filed a Writ Appeal against the said Judgement before the Bench of High Court of A.P. and Telangana in year 2017. High has dismissed the Writ Appeal in Dec 2017. My lawyer is telling me that SC has passed some order, which is directing the High Court of A.P. and Telanagana to dismiss/dispose the Writ Petitions pending prior 2006. So, my case won't get listed till next year (2019). What I can do to get it listed for hearing, please suggest me? Help/Assist me?
