If you are young and don't have a national insurance number yet, ask them to change your account holder to one of your parents and give them the NI.
I'd basically create a website reporting this issue to the general public and attach all emails and information you can get from them. Also, I'd change the payment method in your website to something else LIKE RIGHT NOW! You should never, ever trust Paypal! Like NEVER!
You should also report this to the media, they will love it! $200K is a lot hell of money!
