Got reply from Motiv now.
"Hello Thomas,
It looks like that number just hasn’t been uploaded to our database as of yet, so we will make sure that your serial number gets entered so you can submit the form successfully.
Thank you"
Gonna wait until the PSO replies back to me on FB. Need confirmation that I've entered everything about the pso correctly before I hit submit now.
So which ball should I go with then?
I'd love to have a limited edition ball in my bag.
But I'd also love to have a Paranoia or a Venom Cobra.
