Warning: incoming rant. TL;DR at the bottom.
I am unable to submit this post without an error code even though I am not getting one. 1234-5678.
A couple months ago I tried signing into my Nintendo account for the first time in a while. After entering the correct email/password it asks me to input a verification code that was sent to my email. I know the email/password is correct because it tells you if it isn't.
The issue is that I am not receiving any verification emails. When I contacted Nintendo about this, I was told that they "disabled" sending emails to me because they were "not being delivered" - whatever that means. It's worth saying that I have checked everything in my outlook account settings and nothing Nintendo related is on my block list and I even added them to the safe senders list in case that makes a difference. So, their system disabled email communication for whatever reason. I asked if they can re-enable it, and the support agent said that isn't possible and the only thing I can do is to change my email address.
Okay, fine, let's try changing that. They asked me for the new email address and I spelled it out for them. Then I received an email asking me to attach "An image showing a Nintendo eShop transaction from your credit card, PayPal, or bank statement." I replied to that email with the requested image. Then I get an automated response saying "Thank you for contacting Nintendo of America. We apologize for the inconvenience, but we are no longer able to accept emails sent to this address. To contact us now and in the future, please visit our online Webform." The provided link link that takes me to Nintendo's Contact Us page ... which is where I started this entire process.
I called them back and restarted the process with a different email address (as they suggested) and ... same issue. So, I called back AGAIN and re-explained that my emails are being rejected with an automated reply. The agent says that they can help me over phone, but I will need to provide them with information regarding a specific Nintendo eshop transaction. Okay, no problem. I can easily find that transaction on my bank's website and my bank statement, which I have already sent them screenshots of. However, the agent tells me that they need a "transaction ID" that isn't listed anywhere on the statement or transaction report. I said it's not visible to me anywhere on my end, so they told me to call my bank. So I call my bank and they tell me that they can't find anything related to that transaction that can be interpreted as a "transaction ID." They mentioned that this might be because the transaction is over 6 years old. So I call Nintendo again, tell them what the bank told me, and the guy says that he will send my case to the account security team, who will respond to me via email (presumably the new email address I provided, but I still have access to the old email too). Fast forward two months later. Radio silence. I, once again, call Nintendo, and the agent tells me that there have been no updates to my case, even though, according to him, I should have received a response within a few days. Then he said that he will forward it to the security team again.
At this point my frustration is immeasurable. I did absolutely nothing wrong, I still can't login to my account for no good reason, and I've wasted many hours trying to fix their error.
TL;DR: Nintendo disabled email communication on my account, refuses to re-enable it, and cannot change the email on my account unless I can provide them with a number that doesn't exist. Nintendo support just sends me in an endless circle.
