It could be a technical problem but it’s not a common one or we’d see it mentioned on the forums often. I am not sure how you come up with Fiverr “eating money” since you’ll get your refund. Sorry this happened to you, it’s an odd glitch. You’ve also contacted Support during the holidays so it makes sense that they might be a little slower during a time when USA offices would have closed for a few days.
If you want to try again, just get your refund and do so. If you think Fiverr is bad and that you won’t get a great value (the main reason people buy on Fiverr) then you can always ask for your funds returned to your bank account and then obtain the service you need from a local agency or elsewhere. Best of luck and happy holidays.
