This number called. Unknown to me. No message left so I've presumed it's a scam.

Called number back and straightaway received message, "Due to temporary service difficulties we are unable to connect your call at this time. Please call again later." Hmm!

Flagged by phone as "spam". Blocked

On 28th November 2022 same number called. So I tried to call back & got the same message as on 17th November "Due to temporary service difficulties we are unable to connect your call at this time. Please call again later."
