Need legal help

Hello everyone, hope you all are doing good. I had been working for my former employer's company from December last year and they have unethically terminated me by lying about my performance even though they didn't give me a single performance feedback before terminating me. They haven't paid me my last working month's salary and even calculated FnF amount since the past 7 months, now I have lost my patience and want to seek legal help. Can someone please give me a reliable lawyer's contact?
