VW won't give a sh1t.
They sell millions of cars, even if they imagine you will buy something other than a VW, they won't care.
I agree its not good enough, but they won't care enough to offer any help.
The CS is a minor selling variant of their cars, they probably haven't got production numbers to supply it anyway.
Between Covid shutdowns, semiconductor shortages and electric vehicles, not selling a CS to you is such a tiny problem.
I know its frustrating though - I went through the same to get my Mk8 GTI that I thought was going to be January 2020 but in the end was March 2021.... no product, no demos, no test drives, long order times....
If its any consolation, I happen to know its not a unique VW problem either.... I don't think VW have talked about options not being available...and even in flight orders having them removed. BMW have!
