called back amd diconnected

I called back number (03) 9068 7744 rang once then gets disconnected automatically.

Same as above, offered information without strings but had to drop the information off along with an apple smart watch- seemed dodgy so didn’t commit.

Answered, but wish I hadn’t. Call centre - something about interest rates and saving me money and did I see their ad on Tele (can’t remember who it was). The lady kept saying they weren’t selling anything or wanting us to switch anything. Asked if my address was still current and would I be home next week so they could deliver a package of information. Told her I really wasn’t interested and hung up. I have now blocked them.
