Continually ringing. Nothing on the other end. Blocked number

had lots of calls from this number - all of them nuisance calls.

keep ringing me almost 3 times a week, call back and it's always asking to leave message

Now blocked...

New my name and wanted to know if I owned a business and was working, I answered no, they wanted to end the call then and I asked them to remove my number from their auto dial, I doubt they will.

Calls 3 times a day ! for around 3 rings then hangs up - spam

Called couple of time on different days. When tried to call back no one picked up the phone

Just another serial pest who you don't need to know.

call multiple times per day. relentless and annoying

Two days running now, silence at other end. Nuisance.

Just silence when I called back

Caller asked for Julie Calvin (who is unknown); when asked what the call is referring to, caller hung up.

Caller: Hangs up al the time

They keep hanging up when i answer the phone

Called at 11.45pm lucky the phone was on silent or they would have got a gob full of expletives even a robot would understand

Caller: No idea

Answered - but no-one there.

They just hang up

They constantly ring twice a day at all sorts of times.
Obviously trying to sell something!!!

spam

Caller: SM Super?

Claims to be the leading super (superannuation) advisory service. Has the typical scam call super long silence on picking up the call, followed by a foreign accent...
Googling the name they provided produces no results, suggesting a scam is indeed what they are offering.
