The difference between sending cash and a check is that when a check gets stolen, the sender can report that to their sending bank, which will contact the receiving bank, and sort it out. If it is reported and dealt with in a timely manner, this usually results in the funds transfer being reversed.

In this situation, however, the sender is flat out refusing to take the simple step of informing their bank -- most recently about an hour ago.
