Reviewed your account and case again and I don't see where you are being billed for anything. The amount also doesn't seem to match.
Your Upgrade Plan does have a credit card attached, but that would be an annual charge if you had auto-renew enabled (which you do not) and would be $99 (876.61 SEK).
https://shop.avid.com/ccrz__ProductD...ku=DYNAPA20005 shows the Complete Plug-In Bundle would be $4.99/mo (44.18 SEK) or $49.99/yr (442.64 SEK) so those also don't match the 250 SEK charge on your statement.
Your bank statement doesn't mention Avid. Can you please check with your bank again and respond to your support case if needed? Thanks.
