The recording started off with saying "Hi, this is not a solicitation call.  We have been monitoring your credit card purchases...."  Unfortunately I didn't have time to play games with them today so I hit the # key followed by the * key.  In the past I've found this works to stop the recording and disconnect the call.  Unfortunately that doesn't seem to work on political calls.  Anyway it did work on this call.  The recording stopped and a few seconds later I heard the line disconnect.  Not sure what that key sequence does but it might do more than just hanging up so why not.  Anyway, when the call back, and I'm sure they will hopefully I have more time to play games with them.
