ICMP response time from a router/device is not a great way to judge if there is an issue or not. The devices generally have control plane policing and responding to ICMP is not prioritized at all.
I would suggest your engineer setup something on their end of the connection that you can ping, and start there. Leverage something like smoke ping to something on their LAN, or even the public IP on their RG/Modem.
