I have accepted an offer on Jan 10, and my last working day in my present organization is in 3 weeks.
I contacted the HR who was responsible for my case around Feb 3 on phone to discuss if I can renegotiate the compensation. He said it was not possible at that time.
After some rethinking, I sent an email asking for a discussion on compensation to him again on Feb 22 and also CC another guy to whom I talked first about the compensation before the offer letter was sent.
There is no response from their side yet, also they aren't picking calls.
Should I be worried or should I give some more time and then call someone else asking about an update ?
