What should I help you I dont run the pool nor I have soem system where to rate pools.  on pool page under support you have IRC: https://monerohash.com/#support

Join in and it will lead you to IRC channel that is dedicated to mining. There are different pool operators and different miners. They will most likely be able to tell you if you did something wrong. And since you said this pool support is ignoring your email, that is already strange. People on IRC  will also be able to tell to other miners that this pool operator is a possible scammer.
