Pay just now is a ****

I have been ****med and I tried adding a new card. I spent the whole day communicating with their customer services I can definitely say that pay just now customer service is so poor. I have sent countless of massages on WhatsApp and emails without any help. How hard can it be to add a new card so I can make the payment. I would believe that pay just now is a **** and this is their way of making revenue by making one pay for late payments. While I have wasted my time and money trying to find make payments. The new system is the worst.
