I am a new user of mudfish android app and I purchased this for playing BGMI from Europe. All nodes from India are showing more than 131ms and I am facing a bad gaming experience. I think I wasted money for purchasing mudfish.
Sorry for this inconvenience. When I checked this issue properly, it looks like 130 ms ping is a lowest ping which Mudfish can provide for you.
If you want to get the refund, please check Refund Policy. If you paid with iPhone inapp purchase, I think you need to contact to Apple.
