Other players cannot see my chat

Hello, I've been waiting for a response in-game for around 4 days. This is what happened: A week ago, I suddenly started to lag really bad. I didn't understand why. Then 5 days ago I logged out properly in the town and tried to log back in to a 3102 "already logged in" error. It took several hours before I was able to log back in. The lag disappeared! I thought everything was great until I tried talking to people in ANY chat form. Be it /tell /say /shout /fc. My brother and a few fc kept asking why I was ignoring them. After my brother gave me a call, I explained no one could hear me.

I eventually gave up and decided to wait until the server maintenance. That didn't ****ing fix it! I've uninstalled/reinstalled the game, created new chat windows, reset my chat settings, obviously logged in/out multiple times. Now, I finally get a response from a GM. IT WAS AN AUTOMATED "I couldn't give two sh*ts, go report this elsewhere" response. I've had so many issues with this game since I started playing, yet I continued giving my support. Now, I'm in an online game where I can only read what others are saying and can't send messages out.

*Update* I found out that people can read what I'm saying in dungeons and only there.
