Xfinity blocking SAS airlines website and request to unblock going unanswered after a week

I reported the website flysas.com as being blocked and received acknowledgement of the request.  I have now spent an hour last Friday and an hour today on the phone with customer support and they have no idea what to do.  I understand how sites sometimes get flagged.  But what I do not understand is why it is taking so many days to have it rescanned and then unblocked.  I spoke with SAS Airlines and they confirmed their website is not hacked or held for ransomware or down.  I can access the site on other internet providers or using cellular service.
