It sounds like the customer service rep didn't properly mark your items as picked up on their side. So sorry! The pickup should clear itself from your view as soon as the best before dates of all items have passed.
An unconfirmed pickup does not negatively impact your account in anyway.
If you would like us to clear any orders, please reach out to us through the ‘Help’ tab found in the app or by submitting a request. You can also start a chat with us on this page through the Chat bubble found at the bottom right.
