I looked through our support tickets for your account and don't see anything. If possible, send a support request using the address that is associated to your account otherwise we can't connect the two easily. I can try searching through the ticket backlog for your request, but it might be easier to send the message again using that email.
I also may be able to immediately help you right now: You must provide a tax number to avoid paying withholding tax. No exceptions. Consult a professional or do personal research to figure out what you need to provide, as we aren't qualified to offer tax advice. (Sorry if this is off the mark, but it's common question we get)
Thanks
