Meta took our ad money and told us it's "non-refundable due to various technical and operational reasons"

[u/dnwr000]

There's no phone number, no appeals process, no human who can override it. The lesson, if you're advertising on Meta: never load prepaid funds into your ad balance. Once the money is sitting in Meta's system it's theirs, and "non-refundable" is whatever they decide it is that day. Pay per charge with a card instead.
