Hurts our business and support is crappy

We chose this plug-in and Wallee in the hopes to have an all-in-one payment solution. Unfortunately almost 2 out of 3 payments don’t get directed to the payment provider. The customer instead just gets sent to a confirmation page and we receive a message that an order has failed. This really hurts our reputation and we had several tests done from our side: This happens when the customer wants to pay and the plug-in fails. It’s 2024 and it is simply not understandable how such a company can have such lousy support for something that should simply work!
