If we create the return label in shipment and use as "Pick Up From" "Customer" and as "Delivery to" "Company" it still tries to get the company contact phone from the "Pick Up From" field.

Because the customer is not linked to the company it leads to the error "AttributeError: 'NoneType' object has no attribute 'phone'"
