Maybe try a certified letter first?  Also, they don&#x27;t require YOU to ack, they require SOMEONE to ack, as I don&#x27;t see anywhere where they actually have the &quot;acker&quot; verify that they are the account holder.  I wonder if there is a legal loophole that the account holder could use as they can&#x27;t prove that the account holder is the one that acked.
