Lala company making life miserable

I got an offer from an MNC, but they want me to join on 3 Feb. My official notice period is 2 months in my current company.

I resigned on 2 Jan, my manager didn't respond. I asked him if he could give me an early release. He didn't talk properly, he was angry.

Then the client needed a new feature to demonstrate his business partners. At that point, my profile was about to end if I didn't deliver on time and I discussed this with my manager that the client wants work, and I can handle that, but he will try to give me an early release.

I saved the company's profile by the meeting deadline. Cut to today, I discussed with him if he could give me a date of my last working day so I can plan my switch accordingly with the new company.

But he said, he was busy and didn't discuss with management for my early release. He has to convince them all. I said it's been more than 20 days and you didn't decide, I have fulfilled all my duties, saved the profile and finished the KT part. He just finished with these words, "I'm really sorry, I need to decide it".

Wtf man, he just wasted my time and effort. Why the hell he want me in this company? I have done everything on my side. I did everything he promised.

It was really hard for me to get an opportunity from any company.
