Anonymous gift cards?

Hi everyone I wish I found this subreddit earlier. I got a Prepaid Digital Solutions virtual Mastercard a week ago and I've been trying to get it to work since. I just can't buy anything with it, and their customer support is nonexistent.

Could you recommend an alternative?

I used Entropay and Paygoo in the past but one ended its service and the other I'd have to get physically.

My goal is to make small private payments at online merchants.

$10 in crypto for the best recommendation that helps me most

Help! Thanks
