@Caroline123 It could take a few days for the credit to come through. If you've just signed up I'd wait a few days as CS Agent has been dealing with fallout of system change so they've been busy. If still no notice or credits in a few days, you can contact CS Agent at this link,
They'll be able to fix you up if it's not automatically done.
hi @Caroline123 if you have not waited 72 hours yet, please wait
if 72 hours passed, submit ticket with CS agent and they will add it back
After ticket is submitted, make sure to check your Community Inbox(top right corner envelope icon) periodically for response from PM
If you have problems submitting a ticket, you can open ticket by private message (but this can take longer):
