Scaleway is a disaster in terms of handling payments.

At some point there was a bug in their payment system and I couldn't pay an invoice. The payment failed the first time due to lack of funds on my account (this initial failure was my fault). Once my account had funds, retrying failed with a vague error on Scaleway's side.

I reached out to support, and it was a known limitation: if your initial payment fails, you an only retry with a subset of their supported payment methods. I didn't have access to any of these payment methods, and I made it clear that I could pay, but only with the payment methods we'd been using thus far.

They kept sending me emails reminding me of this overdue bill and threatening to send collection agency, all while I kept exchanging messages with support complaining that their system gave an internal error.

The bill was, by the way, for less than €10. But a collection agency will charge you hundreds for the "collection" service.

They were aware of the error in their payment system, but it seems they had no intention of fixing it. After months of back and forth, they just cancelled the invoice.

The amount of time and stress in dealing with was ridiculous.
