Quite simply: he was being rude and only really concerned with you doing the $ 27 transaction.
I don't give a damn if he's locked up or not, that's not how you treat anybody, especially if you ask them a question and didn't let them answer first.
You hung up on him the right way the first time. You should not have picked up the phone again and as soon as he starts cussing you out, let that damn phone ring for a day or two.
Only consider completing the transaction if he actually knows how to apologize.
