After having my phone ******, I made an order to be instant shipped today; was rushing before a meeting and mistakenly input the incorrect delivery address.

Now I am trying to change the address, but there is no option to do so on the order. There is no option to speak to an online representative etc. I have no phone, so the delivery guy cant call me when they are outside the incorrect place.

How am I supposed to resolve this? You must have some way that someone can actually get through to you for urgent matters?
