Blocked serial numbers on second hand purchase

Still not answered my question number two...

I have five ReadyDuo NAS and all of them bought secondhand. Works fine, but OBVIOUSLY Netgear did think about that as the previous owner is still registered on the serial number I now have. I have tried to ask the previous owners to unregistered from the serial number, but without success.

So PLEASE Netgear think again, and most of all solve this issue by letting me register my NAS towards my own account!

So what to do? I mean it could not be that difficult to see for example where the NAS Duo is and that they had the same IP address, i.e. same owner! Otherwise Netgear will kill the second hand business imidiatly... As a second owner never could register his units on his account...
Right?

Ok, thats really bad! 

Because I think Netgears existing solution for ReadyNAS Duo to get remote access is to complicated and unstable.

The userfriendiness are undoubtedly the most complex I seen in regards to a "cloud service".

So I really hope that Netgear could get a solution for the Redy NAS Duo as these units are perfect to place in your parents home, friends etc to get a good security regarding fire,burglary and so on, and the unit could be easy accessible and dont need a lot of space at your parents place etc.

So I really hope that Netgear reconsiders, and at least create a light version for Ready NAS  Duo...
