Wordpress Login Error due to 2-Step Auth

At first, I created a wordpress account. Then, enabled 2-Step Authentication via Google Authenticator on Android.

Then, it worked well. But, I deleted my app. After that, I tried using one of the 10 backup codes to login, but they all failed. I also re-installed the app, but the codes are not working now.

When I click "Send recovery code via SMS" on wordpress.com, I do not receive an SMS.

Is there anyway I can get this to work? Please help.

Thanks in advance,
Champ.
