Weird Ping Problem

I live in the Philippines... and I play RGC on PH channel.
My problem is high ping in RGC.
Before I get 60 Ping... now I am getting 150 - 200 ping. ( restarted, re-installed doesn't work .. )

But I found out that it's NOT my service provider's problem ( PLDT )... I think RGC is the problem...
because when I play in Garena, I get 60 ping...
It has been like this for a week and I can't play in RGC :(

I hope I get solutions for this problem .
TY and long live RGC <3
