From my own experience, you may have to wait for at least 48 hours if the agent assigned to your ticket really take care of his business. I am lucky to have the second ticket assigned to Silvio_M, he solved my problem on last Sunday!
Hello guys, my problem got solved after I submitted a ticket. The agent Silvio help me first after the ticket assigned to him, then I told him I had the the issue with my son's, I just told me son's number, he made that number work as well. Fantastic...
