My Emirates online profile Passport expiration date is incorrect.

The expiration month and year are correct. The day is not. I'm worried this will wreak havoc on my upcoming DFW <--> DXB flight.

1) Tried to change it online, on my laptop browser, both in Safari and Chrome. Emirates website will not allow me to edit that field.

2) Tried to phone.
"Due to the high volume of calls we're experiencing, we're unable to take calls at the moment."
Wow! No calls at all !

Why would you recommend?
