Q: “Your Purchase Could Not Be Completed. For assistance, contact iTunes Support at www.apple.com/support/itunes/ww/.”

same problem here

Have you done as the message tells you and gone to that URL and contacted iTunes Support ?

yes. problem still unsolved yet and support is contacted again.

Have they replied saying that it should now be fixed ? And if they have, have you tried logging out and back into your account on the device/computer that you are using ?

They have and it didn't fix anything. I have tried any reset, restart, logoff, etc.

Very unsatisfying start with Apple. The brand new iphone 6s plus 128gb is useless without the ability to purchase required apps.

Update: The support seemed to have fixed the issue. There was no reboot/login etc. required.

Hopefully, the problem won't come up again....

You have to do as the message tells you and contact iTunes Support, these are user-to-user forums : http://www.apple.com/support/itunes/ww

Contact iiTunes billing and verify your billing information on your device in settings > iTunes and app stores> select the apple id and you will see a drop down box to >View the account> make sure that your credit card and address info is up to date along with the CVV code and the Mr, Ms, etc.

Try the purchase again - if that does not work contact iTunes Billing and they should be able to clear up any delayed holds on the account.

Not sure why you are replying to me, I'm not getting a message to contact iTunes Support

Having this same problem as well. Attempting to make an in app purchase but it won't go through even though I have sufficient funds.

And what happened when you contacted iTunes Support?

GB

I cannot purchase coins for a slot game.  I wish this would stop happening.  Please fix this for me because every time I try to buy something it rejects me.  I would appreciate your help.  Thank you  Gertrude Katz

Nobody on here can fix it, we are all fellow users, you need to do as the message says and contact iTunes Support via the URL in the message.

Same problem here, why apple is not responding are they dead?
