If Yumilink had your data
- Look for Yumilink’s own notice or letter: it should say what of yours was involved. Keep it.
- Expect scams that use your details: calls, texts or emails pretending to be Yumilink, your bank or the police. Never give codes or passwords, never approve a sign-in you did not start, never move money.
