I can assure you that this is not a cache problem.
To start, devices that never accessed the site can still access the site from my end.
Second, the paypal payment went as purchase, not as transfer for friends or family.
The e-mail from the paypal account seems to be connected to other sites that also sell these kind of devices, I checked the e-mail before payment, that's why I went with it.
Infact, it seems the e-mail as been around for quite a while.
So, in paypal end, no worries, it is treated as a purchase, if no item received, you have 180 days to make a case.
As for the website, it must be country blockages due to multiple domains.
No reason to flip out: 1st) you're 100% protected by paypal and 2nd) internet is an un-stable thing in these kind of things.
So chill. =)
