There is no immediate action you need to take, and nothing to cancel.
It is worth staying alert to unexpected emails, telephone calls, text messages or social media messages for the next while, particularly any that seem to know about your connection to SCA UK. If you use the same password anywhere else that you have used with us, it is a good moment to change it.
Beyond that, please do not feel rushed by any message that creates a sense of urgency. That pressure is itself one of the clearest signs of a scam.
