Thousands of affected customers, no stock of alternative cards, not enough manpower to have a discussion with every customer.![]()
How about sending an email to everyone in a queue with a web form link containing a few options?
No extra discussion required and depending on response they can be processed in batches.
E.g.
a) cancel
b) pay uplift of £X
c) change to a different model entirely at new £RRP+++++ (Intel stylee) - maybe that's a multi choice option on it's own
d) go nuts and upgrade to a 3090 (lottery winner option)
