Project release mail from rmg

I received the project release mail from rmg and i have to report to rmg from 30th and my allocation is going to end on sep 30. But the manager messaged me over whatsapp that there is a 10 day buffer time. I asked for release almost a year ago and after so many delays and extending, they said they finally got my replacement and got the date this month .they can only onboard the new guy if I'm released. I came to know I'm already in the fluidity list by hr even though i was working extended shifts and also during severe illness. I also came to know by a frnd in rmg that the name is given my managers.

I did some interviews inside tcs, they asked for release date and when checked, they informed me they are not able to pull me or allocate me as I'm in the list.its very difficult.

So will the allocation be extended for 10 more days? Or should i start reporting to rmg from the 30th, and what is the point of reporting as no projects are able to allocate me. Kindly advice
