I have joined the company last year but after 1 year my new company started BGV and told that last company is in suspect list they want my form 16 and bank statements, I don't have Bank statements because customer ID is not working & also Hr told me that they will send form 16 they didn't send it now no one are responding & also i don't know whether company is still exists, what should I do,i should put resignation or else wait for the company decision

How can you not have a bank statement?
Surely you kept copies!

Otherwise, you can always go to the bank and ask for the copy of your statement. They are bound by law to give it. They may, at most, charge you for the same.

Form 16 would also be available to you on the Income Tax Portal. You should be able to get a copy or show tax deduction in the 26AS.

If you don't have that also, then even I doubt whether you worked in that company to just took fake documents.

I don't see why you need to resign just yet. Logically you should communicate with HR and explain your position and wait for their decision.
