Can anybody open the live chat session at https://www.zulutrade.com/support? I've been going round and round with the help desk at zulutrade.com. I can't sign up with them because they can't send an SMS to my phone. They recommend I live chat but I can't open a chat window... They have been telling me to try different browsers with popup and ad blockers disabled and I have done that but still doesn't work.
