Used their Moneygram service 3 times. The first 2 times it worked well. But the last time was horrible. They confirmed my transfer. I transferred the money into their account. In about one hour they called me to let me know that they are unable to perform the confirmed transfer citing a nonsensical reason. And the challenge of getting my money back from them took about 3 days. They seemed rather incompetent while dealing with some glitch in their system. I still don't understand the reason why they couldn't make the transfer or why it took so long to return the money. I'm not going to use any OzForex services anymore.
