What to do if (866) 837-3456 contacted you

1Do not reply or confirm anything. Even "wrong number" or "not interested" tells them a real person owns the line.
2Do not give a card, bank or Social Security number, whatever they offer. A caller you did not contact has no reason to need it.
3Do not call back. Returning the call confirms the line is live and can put your number on more call lists.
4Block the number on your phone, and report it. Reports help move a number onto FendLand's shared spam list.
5Get off the source lists. Spam calls often trace back to data brokers selling your number, so run a free exposure check to see who lists you, then use the removal guides to get off them.
