I've experienced the same as other people. I ordered a replacement bowl on 12/11/17. After days of no response aside from the initial confirmation, I emailed them. No response in the 24-48 hours stated in the the auto reply. I called and waited on hold for over an hour with no one every answering.
I suspect it's the same case, that item is backordered. Not that I could confirm this, since they can't bother to get back to me or answer the phones.
