I am sorry you feel like this. I love to help people and I do it in global because it's nice to help people in need. If you ever need help or have a question, feel free to /msg me.
Sad hard truth is, Builders, Residents, and yes, sometimes even Mayors will get ignored in chat. And not just because someone missed their message. I get ignored by presidents plenty of times. Some people even ignore me on purpose. There are nice people out there who will help you, even besides staff, just keep looking
