Why is Vietnam’s e visa so garbage? My application remains unpaid but I was charged. It’s been a month

I searched reddit and tons of people seem to have issues with it. I submitted two e visa applications. The first one said it was unpaid, i searched what to do and it said I would need to submit another. Neither went through properly. It said payment failed. I was charged for both of them. This was a month ago and they both still say unpaid when I search on the Vietnam e visa website. How do i properly submit a e visa application and how do I get refunded for the 2 i already paid for?
