@Kiran_G hope Upstox is cdsl
- Transferring only stocks ? - use cdsl "easiest " - best of all options
- mutual funds included as well ? - Try transferring stocks first and mutual funds any way will take 1 months to get transferred so get the hard copy and submit
- Digital singnature is equivalent to orginal copy - try to educate him - else complain with local police / atleast threaten him he will do immediately.
I faced the similar harassment from ICICI direct one of the worst brokers out there , They do these nasty tricks so that we will be locked in their eco system . I had to quarrel with many of their employees to get to know how it works.
with ICICI direct its fairly simple now - close the account immediately and give the transfer out request they have to dump everthing to your zerodha with in 7 working days
I am sure with Upstox it is the same procedure , since you cant get the original best is it to use" easiest" in cdsl account.
