These calls are coming in two or three times a day using different telephone numbers with recorded messages. They hang up immediately when you ask to be removed from the list.
They try to sell you "don't know what", claim to be able to make you financially free, they ask for your credit scores, works, salaries and asked how much you are willing to invest to be financially free. If you decided not to do business with them, the person gets pissed off and call you an idiot. Just answer the phone and tell them not to call you anymore!
