Why did he call them? That was a waste of time. That was unnecessary and
99% of the time NSI phone staff don't even know what they are talking
about anyway.
You request a registrar transfer at the gaining registrar (in this case
OpenSRS). You never contact the losing registrar. So forget about the
call to NSI and just submit a registrar transfer request.
