Sounded like telemarketing to me. They didn’t hang up quite in time and left a three second voice message. You could hear other people talking and the words your bank mentioned. Might be some sort of cold entrée. I can see two other people have searched this number recently.

Like others - a missed call but no message and no follow up. Assumed spam

Caller: Spam

It came up as "suspected spam" when they called at 6pm so I let it ring out. They left no message 🤷‍♀️ must be spam

Got a ring from this number - one attempt, no message. Spam dialler pattern.

Missed call, but surprise surprise they left no message. Presume a spam call. F'ing annoying
