Caller: Superannuation review firm

It’s a superannuation review firm, they called me from a dozen different numbers until I finally picked up and told them I wasn’t interested

I called back number 0479 038 546 was put on hold music but no one answered the call.

I didn't recognise this number, but answered anyway.
There was alot of noise on the other end, but noone spoke, so I hungup. I assume it's a telemarketer??
