We used to have 1 every month of so, now we have had around 7 in 2 days.
[EDIT] - I received an email from Stripe a few minutes after I submitted this post on HN. It seems there has been an issue with the management of SEPA payments between end of september and start of october.
[EDIT 2] - I actually received the email before submitting this post, I just did not notice it ;)
But it's funny that someone can win on a "fraud" claim when it's a renewal of a subscription that they themselves signed up for. IIRC to win on fraud you have to show proof of signature or ID or something, to prove it was that person who signed up. Of course, there is no reasonable way to do this online, and the banks just happily rule in favor of the customer.
What kind of dispute claims do most of your customers make, and what kind of evidence do you provide besides USPS tracking?
