Not yet. This was the latest message to me on Tuesday

"Hi (my name withheld), I've heard SFA from the post office. I filed a police report. They're not going to be of much help either. They've already made up their mind who did it. I filed a request for compensation from the post office today. They quote a neat little sub clause which states that anything worth more than 100 should be insured. Any progress at your end?
Regards, (name withheld)."

I am not really sure what to make of this. I said to my business partner today that it is quite strange he has not opened a dispute as yet given his aggressive opening to me in the messages outlined in the OP.
