TF2 - No mics or chat

Hey i got my account cut from chat & typing on Team Fortress 2. Has anyone had this issue and been able to fix it? How do i get off the black list?

Private server?

No. Im on the regular one.

Did Valve issue a notice of it?

I don’t cheat, bad mouth - nothing, and i’m a 5 yr playa.

Eh open a ticket with them then

i can do that?

yeah in steam client
