KC servers cannot be pinged using standard ICMP pings. This also implies using tools such as tracert that is provided as part of the standard windows CLI tools.

You also didn't try enough VPN. How many have you actually tried? This is definitely a networking issue and if your ISP does not have a clue on how to fix your issue I suggest you to switch to another ISP - one that has more clues. This is definitely a routing issue and the standard windows tools isn't adequate enough to solve the issue.
