Game customer service non-existent

Game's customer service is non-existent. I received my monthly bill and it stated that I have an astronomical amount of money outstanding. I have sent them 3 e-mail's requesting a recon of my account, explaining why my calculations are different from theirs. To date I have had no response, not even an acknowledgement of any of my e-mail's. Thus far they have blatantly ignored me and no-one seems interested in the service part of customer service or in giving me answers about my account.
