Ebucks purchaes don't work at all. They credit them but don't finish the order

I am extremely disappointed. I have used them for many years. I purchased an Xbox voucher with ebucks and they credit the ebucks but don't process the voucher or order online at all. They just stopped it. It first went from the app to an its website to process the ebucks payment. However on that page after crediting my ebucks it doesn't move to the next screen just takes my ebucks. It did not say the order is complete in fact it still leaves it in my cart whcih means the order isn't complete. I checked the order history and to my surprise it's not there. No confirmation email nothing. All I want is just a refund I won't ever buy vouchers here at all
