I am posting here as I have not received a reply to my support email.
I updated my auto-renew information (after the previous auto-renew attempt failed due to a new credit card) and was told that the auto-renewal would occur in 4 days. However I got a call from my credit card issuer saying that my card has been frozen due to suspected fraud with a charge of $0.96 AUD (approx $1 USD) from wordpress.com
Does this mean that I am being charged for a failed renewal, or that the card is being tested to see if it will work on the auto-renewal date?
There was no documentation, warning or receipt for the transaction that occurred.
