Getting SQL support from Microsoft

Any got a trick to open a ticket with MS for SQL support (Paid)?

We have CSP licenses, but CSP will not take a SQL ticket.

I tried online, but it makes you use a personal account, then errors out.

When I phone it says you can only open SQL tickets with web.

We just have a urgent problem, and I think it's simple for a SQL expert.   Should not be this hard to get support.  Used to be easy.

(BTW I am the MSP - they cut off our old way of opening tickets)
