SOLVED: hoping to help by sharing a very similar experience I was having with not being able to use my apple account balance toward a product purchase through apple’s website. I received a gift card and had redeemed it to my apple account, but could not find a way to apply it to a purchase.
Like many others on this thread I went through the extremely infuriating and cyclical experience with apple support via phone, being transferred back and forth between sales and support and getting a multitude of unhelpful answers. On two of those occasions the operators told me I couldn’t use my apple gift card to purchase apple products (only apps, music, etc through the app store), which is in direct contrast to the fine print on the actual apple gift card. Don’t take this for an answer!
After being told someone would “look into my account within 24-48 hours”, I impatiently continued to try every solution suggested on these forums — I reset my phone settings, tried to remove and add the account balance to my apple wallet (a whole other issue), downloaded and installed the latest software update, all to no avail.
As a last ditch effort I downloaded the Apple Support app and used it to text with their support team regarding my case. I highly recommend this option as it was MUCH less time consuming and painful than using the phone support system (no waiting on hold and you can send screenshots as needed).
While I still had to go through one operator who couldn’t help, he was able to finally transfer me to a “specialist” who solved it right away. Her solution involved removing the apple care component of my shopping cart, and like magic i was able to finally redeem my account credit toward the purchase. I’m not sure if she did something else on her end, or if the elected apple care coverage was the actual culprit. Either way, you can add apple care within 60 days of purchase so her solution worked well for me.
I’m usually a big fan of apple, but the amount of people having to go through these hoops just to be able to use their own money is absolutely unreasonable IMO. I hope they can correct this issue soon or at least have more knowledgeable staff to aid in the process.
TL;DR: use the Apple Support app instead of calling to maintain your sanity, and try removing apple care from your cart to use your apple account balance toward a product purchase.
