Which user did not receive a response to their ticket, can you please share the username with us?
So I can share the screenshot.
I am the one who get no response for my ticket, the only reply I received is just something like an automatic reply by your system as quoted below:
This ticket was created on your behalf.
Above reply was sent within few minutes or maybe seconds after I created the ticket through your ticket system.
Coming up to my username, you can re-check your private message as I was one of those who claimed the €5.00 Welcome Bonus for BitcoinTalk and I've sent you my username by pm 20 days ago.
