Hi,
I think there is a problem with return adress.
I invest 0.001 btc on your site with a Xapo wallet.
My return adress given is : 3G8rycwyrJtaHtPzGNCN7rzG31QY84f7ic
Your automated process take the Xapo adress for return : 3C4ABC7iPcAAKBh6SJXfvUSDBew3abCtw3
You never mentionned, we cannot use online wallet !
If you can correct it ...
Thanks
