Poor phone support is a sign of a fake website!
Lenny Zeltser in Ouch | November 2017 says:
Verify the website has a legitimate mailing address and a phone number for sale and support-related questions. If the site looks suspicious, call and speak to a human. If you can’t get a hold of someone to talk to, that is the first big sign you are dealing with a fake website. (emphasis added)
Even outside holiday shopping (the subject of Zeltser’s post), message only and deep phone trees merit a copy of Zeltzer’s column.
