If I have understood you correctly.......

Irrelevant of your RP renewal and contract timelines, you should be able to carry out the following-:

1. resign as per your contract terms for the same, or if not mentioned, then as per labour law.

2. receive your end of service benefits as per your last basic salary. I believe this is how it works.

You have all the proof, so should all be ok. Check the labour law online though.
