I received this from Tesla support, looks to be a system issue their end.
“Please kindly ignore the email. While it did come from Tesla and is not a scam, this shouldn't have been sent. Tesla erroneously posted 1 GBP to your account yesterday and when the amount was removed again, this action caused the automated email to get triggered.
You do not owe us 1 GBP and should not wire the amount to the account mentioned in the email”
