cut your losses, get full refund.
buy another set of wheels which are less complicated, less highly polished and therefore less likely to deteriorate.
I suspect you will in time, again have issues with the other wheels.

Polished wheels are shyate and will always fail. Like having a tart on your arm, may look good but they will not be with you for the long term.
Take the refund, sell the tyres to a C63 owner (they are the same size) or buy new wheels that can reuse them.
Buy a new set of painted wheels - get done decent OEM ones, don't p1ss about.
