Payment on hold

Has anyone experienced payments on hold ? 
eBay want me to sent items I have sold without being paid . If I was to do it today I wouldn’t get paid until the 20/06. 
I am a top rated seller with 3/5 star reviews and 1/4.9 review and all excellent feedback from my buyers . 425 transactions this year and all loaded with tracking and no late transactions . 
eBay seems to be kinda bullying me into sending items out before I get paid , has anyone experienced this ? I have been on eBay for 19 years it just doesn’t make any sense . Chatting to eBay I just get we have escalated your case and you hear back from us in 24 48 72 hrs but nothing . No one seems to be able to tell me why my payments are on hold . In meantime I have all these items sold and I ain’t sending out until I get paid . Sounds like a scam sending  items out before I get paid .
