Thanks to the wonderful advice I got on here, I paid off my DM's natwest mastercard, in fact I overpaid it by about £50. Out of the blue she has just received a letter with a cheque for £20 saying only here is a cheque as the mastercard account is now closed. Her own bank account (also natwest) is still active and not overdrawn. Is this normal? She'd received no other post informing her that this would happen (I know as she gives me all her bills and bank letters to deal with at the moment). She has paid the minimum interest payment by direct debit for a few years, until I paid it off in a lump sum as things were getting on top of her. Now the card is suddenly cancelled?
