So I just went to the ATM to get some cash.  I input that I needed 100 pounds but I only got 80.  I have the receipt  and I am in need of the extra money.  How do I go about obtaining the missing amount?
What should I do if my card is compromised? What should I do if my card is swallowed? How do I get a spare card? What should I do if my phone is lost or stolen? Why is my PIN blocked? Why is my balance not updated after a cheque or cash deposit? Why do I need to verify my identity? How can I exchange currency via the app? Why is there an extra charge on my statement? What is the charge for topping up by bank transfer? What are the limits for disposable cards? What is the current exchange rate? Why is my top-up pending? What are the top-up limits? Why has my transfer not been received by the recipient? How do I top up by cash or cheque? What is automatic top-up? How do I cancel a transfer? When will my card arrive? How do I terminate my account? Why is my card not accepted? How do I verify my identity? Why was my cash withdrawal declined? Why is my card not working? How do I verify the source of my funds? Why is my contactless payment not working? Why is my card payment pending? How do I change my PIN? Which fiat currencies are supported? What is the charge for currency exchange?
