Utterly frustrating experience
I registered yesterday to send money to my sister from the US to Europe.  That went OK, but the next morning when I logged in to send her money, my login failed with "Error - Incorrect phone number" or somesuch (it's now a different message after trying all morning to make progress :"Your user or phone number has been blocked from sending messages. If you believe this is a mistake, please contact us.").

Perhaps the login code didn't like the hyphen I have in my email address, and mistook it for a phone number.

I tried to use the web page to email someone about my problems, but upon submission, I got an error message saying it was unable to process the request.

I then installed the Android app and tried again, with the same result.  

I then tried to register with my Google email, and made some progress, but had a real struggle putting in the recipient's address, since it insisted on using my contact list and putting in the wrong address.  I wound up having to delete my contact and re-enter it so I make progress.

Then, just when I thought it would go through, it informed me there was an account registered and I would have to go into that and change my email address if I wanted to use this one.

I then tried to call the 888-870-2221 number, option 2, and it just rang and rang and rang and rang and....

Forget it.  I will use another method of getting money to my sister.  And I will never, EVER, recommend this pile of excretory code to anyone.  EVER.  In fact, I will urge anyone to stay far away from this company.
