MARIEMUR review for AfterShip Shipping + Labels

We used this service for a long time along with Aftership Returns Center. I would like to express my dissatisfaction with the way they provide customer service. We faced some kind of glitch or bug when we are not able to add card details, every card we add is rejected (all the cards are ok). As a result we cannot buy return labels. This issue has occurred more than 1 week ago. Their customer care team provides me with templated messages and tells me to replace the card. They don't even take into account that every card we add is rejected. No one can help us and our business is completely stuck if we're talking about returns. I am extremely unhappy with this service and seriously looking to switch to another application, because when no one can help you resolve simple billing issue for more that 1 week, this is really weird and looks like nobody cares about you as a customer.
