Ok, fair enough. Email is an unreliable form of cancellation for a number of reasons. I don&#x27;t necessarily buy it, but let&#x27;s accept this for the sake of argument.<p>But then how exactly is it more secure to accept a cancellation by Random Dude on the phone?<p>Except to make the customer (especially international customers, which may have to call in the middle of the night and who may incur significant charges) jump through a whole lot of hoops and to make it as difficult as possible to cancel.<p>To me this reeks like a shit ton of bad faith by the service provider, which has nothing whatsoever to do with security.
