Absolutely shocking. Sign up, then they completely ignore you from that point on. They don't answer phone call or emails. Total waste of time and money.
Had to fight hard to get my money refunded even when they admitted they were at fault.
This was a Melbourne based Barter Card group. Not sure what the others are like, but no one from any of the Barter Card offices in Australia would return my calls or emails.
Terrible. Don't sign up.
