Caller: Company about online investment opportunity

They lady sounded like she rang over a computer and I couldn't understand/hear all the words she was saying. She said I had entered my email about online investment opportunity (which I didn't) and I had been recommended to them. I told her I hadn't done that and can I please be taken off the list she asked me what had changed, I said I hadn't entered my details and I wasn't interested can I please be taken from the list and then I couldn't hear what she said and I hung up.
