It is a solar company

I called back number (07) 3056 0520 rang once then gets disconnected automatically.

Called the number back, some bloke answered after 4 rings: No “hello?”..
just bluntly: “did you get a missed call from this number?” I said who is this? And all I got was “sovereign” before I hung up
No idea who sovereign is but if they’re trying to sell people something they’re pretty sh*t at it...

Caller: Sovereign Solar

100% legit solar company

I've had this call a few times. Now blacklisted.

Did not leave a message, tried to call back, no answer, they call at all times of the day, expect a scam

This number is a scam

Caller: Solar scam

Keeps calling at odd hours

Call number back,
"Due to temporary service difficulties, we are unable to connect your call at this time".
Possible spam, idk.
Definitely not a local or business tho, probably call centre robot?
