Not only telemarketing but clearly computerised as when answering i have to listen to music (always the same) for 10 - 15 seconds before someone picks up the phone.
They call 3 or 4 times a day.
I answered the phone, I heard hold music. I waited about 20 seconds (incredulous). The person asked for me by my legal name (which is not a name I use publicly). She said "You're obviously interested in making a secondary income from the financial markets." I answered "What are you talking about? You called me." She hung up without saying another word.
Called claiming I wanted to learn how to trade. It may have lead on to some scam or pressure selling, But when I asked them how they got my number a few times, They hung up.
