Fiverr throwing error "unable to complete payment. try a different payment method"

Everytime I try to buy a gig using old/new Fiverr profiles, it throws this error. I am using real cards, tired different bank, same issue. I am able to add the card to the account which takes a small amount, but no payment success while purchasing the gig. Support not at all helping, sending copy-paste answers.

I tried anti detect browser, quality proxy, real mobile ip, still same. How the review sellers in BHW doing the payments. I just wanna make 2-3 purchases to boost the gig, but not at all working. Any guide? The cards have international txn enabled, works on all other sites, but not working here, no message from bank means it's not even processing.

Tried paypal yet? Use those cards on paypal and then make a purchase via paypal.

Also, try contacting them on social media, they are responsive there.
