They owe me and 2 friends money

They owe me and 2 friends money. We played a duo a month ago, they just took the money and never rewarded us our prize, the next day it happened again. They said they will refund us within 5 days and its been a month now. They refuse to further reply on our mails. Another friend of mine who stopped zleague and stopped gaming altogether because zleague took 110 dollars from his account without ever replying to his emails or refunding him. Zleague used to be good when it started a few years ago but now its just blatantly ****ming people, you also play vs bots now which will always get a better score than you to prevent you from making profit. We paid memberships and cannot play because zleague is basically robbing us
