Hello. As a Platinum member I have not had 1 single upgrade in years.
Many agents when renting indicate that the site does not offer upgrades,
or that being Platinum in Europe "does not entitle you may get an upgrade even if we have cars available".
no bonus points....in fact no points at all...
Maybe living in Spain means no benefits?
As a "birthday suprise" I got this cyberattack issue with prevents SIXT from doing almost anything 😂
