My last working date as per my notice period was 3rd November, and the HR and RMG asked me to consider 16th October 2023 as my last working day. They (HR and RMG) said that they would pay until 31st October. I received my FnF, and I was paid only for 16 days. I sent an email to the HR and FnF team, but no one has responded for the past two weeks despite reminders. I trusted the HR as this company has received awards for being a great place to work with good employee relations, and so on. What legal options do I have if the HR turns out to be deceitful? Note: The HR mentioned in a telephonic call that the company would pay.
