I have lost quite some money with this provider. Because of a writing mistake when sending the money, they receiving bank send it back to Xendpay, for security reasons. After explaining the situation by email, several times, I have received a short message, saying, they have sent the money to the vendor. After asking them to check again, since the bank has sent a notification that they sent the money back to Xendpay, I have not received any reply from them. In the end, I have lost all the money I was planning to send to my production - their payment - and have to pay it again - out of my own pockets.
I would NOT recommend this provider at all. Mistakes can happen, but providing such a horrible customer service (none at all really) shouldn't happen to any company working in this sector.
