I made an order for a new iPhone 6S yesterday night, and the order seems to be still pending because I have not received any confirmation emails to inform if my order is completed yet. Now I just want to cancel my pending order. However, it seems there is no option to do that.
It is quite simple to cancel your Pre-orders or pending orders on Apple Store. Look at the following steps.
Login to your account, then select View My Appie ID.
Click on Manage Pre-orders in the Settings section at the bottom of the Account Information screen in iTunes on PC.
It is very clear now to click on the Cancel button next to the right of the pre-order products you want to cancel.
There must be a quicker way to cancel your pending account on Apple store. Just chat to Apple support. After a few question to confirm your information, some one will call you to accomplish the rest of procedures.
