I started my order at 12:00 am pst- was told sept 19th arrival. Confirmation email says sept 19th delivery date. Checked online order status- it just switched to"unavailable" we ordered a grey 6 64 gb and a grey 6Plus 64 gb. When will my device ship? Is my confirmation email guarantee? It does not say "estimate", it says "deliver by 09/19/2014"- can someone from verizon please clarify?
