The only way to amp it re paypal is to call again and ask for it to be added to the Alpha Tech complaint file they are now aware of the failing to meet delivery and expecting calls.
So everyone who can call please call paypal ove the next few days so it emphasises the imperative msg that these funds may be up to no good.
You could also try to write to the now-CEO of Paypal, John Donahoe.
When others asked then-CEO David Marcus for a refund of Butterfly Labs orders, I did too and it was successful, even though the 45 days period was long over.
