Anyone else been incorrectly charged for Sponsored Ads?

Noticed we had a charge on our (bank) account from Amazon sponsored ads for a much larger amount than we could possibly be due.

Contacted support who have told me it’s a “known issue” and as far as they know it’s in the process of being refunded, but of course will take 3-5 days to be processed and show back up in our account.

Apparently something to do with everyone’s advertising “credits” being turned into debits and, obviously, immediately charged. I had no idea we have any kind of credits, particularly given that we are normally charged for any advertising spend we make.

Pretty annoyed that it’s an apparently “known issue” and yet nobody at Amazon has got in touch in any way to let us know we’d be affected by it.

Just wanted to see if anyone else has had this issue and to see how widespread it is?

it can take up to 3-5 working days but it might not always take this length of time.
