Hello, how are you? Well, years ago I bought an LFS S3 with an email that I had access to. After a while, Hotmail blocked it and I was never able to recover it. Now I can't receive the unlock code because it sends it to the blocked email. I tried to change it from my account options, but I couldn't. I contacted support, but I haven't received a response. Is there any solution?

What do you mean exactly when you write "but I couldn't"? What didn't work?

You have to wait 7 days before you can change your email address.

It was sent to your old email address which you don't have access to. Now you have to wait until September 8, then there will be a link to send a confirmation to your new email.
