problems with "i cannot spend my money pls fix" were always handled with a higher priority in my experience even for lower amounts. tried to buy a 20 and a 10 pack back-to-back both via paypal but after the first i received a message like for security reasons i would have to wait another 24h hours to use paypal with them again. Ticket => block lifted within 30minutes and i was able to buy the second pack
"Shut up and take my money" problems always had rather good response times - unless you send it in on a Sunday night or something.
After a bit of poking around i doubt he will get the answer he hopes for but of course it cannot hurt to try.

I mean the worst answer he'd possibly get is "sorry thats not possible. to buy for 2k you have to buy 20 times the 100 pack".
