| Accounts affected | 76,682 |
| Sector | Digital services |

| Status | Confirmed |

## Exposed data

- Email address
- Full name
- Phone number
- Postal address

## What you can do

- Expect phishing attempts quoting your name and this company. A message that knows your details is not legitimate for that reason.
- You can ask the organisation exactly what was exposed about you (right of access), and complain to the DPA if no answer comes within a month.
