annoying getting through to my answering machine and not leaving a message-call back tells me number not connected --total scam

After the silence the guy told me I registered online to trade with them. This was the second call and I advised him to take me off the list otherwise I would lodge for harrasment. He then told me to Shut the f*&k up.
Dont think i will trade with.

received a call, no one answered so I hung up.

Multiple calls. Caller doesn't respond. Hangs up after 15 seconds

Someone wants me to trade in forex. says I left my details on their website.
