Looking for a AS15169 Google contact to update their PeeringDB records

Hi, We're noticed that PeeringDB records of AS15169 in IX.br (PTT.br) São Paulo is outdated. I've tried to contact AS15169 to update it via IX Session Turnup ticket and noc@google.com but didn't get a reasonable response. That's what I got from noc@google.com:

Dear Team, Thank you for contacting the Google NOC, as 15169.
