You return the equipment as not suitable for the advertised purpose
and demand your money back.  Renumbering is expected to occur with
IPv6, part of renumbering is getting the name to address mappings
right.  With DHCP the DHCP server normally does it.  With SLAAC the
host has to do it as there is no other choice.

Here in Australia it is Repair/Replace/Refund if the product purchased
is faulty.  That applies to all products.  If the milk is off when
we get home we go back and get it replaced and if the store is out
of stock we get a refund.  I've returned and had replaced plenty
of stuff over the years.
