ICMP traffic limit on Google Cloud Plataform

A few weeks ago, we noticed the loss of ICMP packets sent / received between the networks of the telecommunications operator Telefonica / Vivo of Brazil and the Google IP addresses in the United States (US Central).
A server (VM) monitors our services on Google Cloud Plataform and faces the problems of false positives and service failures.
We talked to Telefonica / Vivo in Brazil and they told us that it was a limitation imposed by Google for this type of traffic with this operator.
Is there a group collaborator who has this difficulty either, or do you know how we can get Google to solve this problem?
Thank you.
