Hi, you should always be in credit by roughly 1 months DD at any time.
So if you're way over that in credit, you can ask PP to review and refund.
You need to send your message to the team directly via Wattbot.
if you go to the app and click on the 3 lines at the top right, then click on help, then ask Wattbot,
Then you need to type in 'message the team' , press enter
then you can send them your message. Might take a couple of days to get back to you, but they will.
