Oh, such a pity we got this type of drama 
My experience with this service was very positive so far. I've been using their Visa card since June and paid both for different online services (Google Drive, online games subs, Amazon Lightsail) and physical goodies with delivery from european shops. Got 0 problems with the card. The only time I got transaction declined was the shop that required the card of local banks (so its not a fault of the service since any foreign card wouldn't work).
Also I had to make one refund since the shop couldn't deliver a product I have already paid for. Got the refund back on the card balance next day.
At the moment I think that if you use this card properly and don't participate in any scams or suspicious activities, it's quite reliable.
