Snapchat restored after mailing HQ (Addresses inside)

I've seen quite a few people mention that sending a physical letter to Snapchat helped get their case looked at after normal appeals were exhausted.

For anyone who's been looking, these are the two addresses that are most commonly shared:

Snap Inc.
3000 31st Street
Santa Monica, CA 90405
USA

Snap Inc.
2772 Donald Douglas Loop N
Santa Monica, CA 90405
USA

I'm curious if anyone here has actually had success with this method.

• Did you send to one address or both?
• How long did it take to hear back?
• Did they contact you by email, or was your account simply restored?

It would be great if people who have tried this could share their experience so others know whether it's worth the effort.
