Cryoset online store - what happened?

The owner of Cryoset store, Ron Sheldon is not answering my emails. I have placed an order and again... no processing. He used to be a responsive person. What happened to him? illness?
Maybe someone took over the company, you know, if you got a confirmation no. He passed away a year ago.
I placed the order on 28 Oct 2019. Got a return email, the sender : Ron Sheldon, with order number....   Strange, scary..
