go to any station and talk to a member of staff. They are generally pretty helpful!

Thanks very much for your help

Just a note about getting a refund on the balance of the Oyster Card - if it's less than 10 pounds, you can use a pay machine at a Tube station. Something I didn't realise though, was once that's done, you cannot use the card any more, you can't load money on to it. To buy a new Oyster Card costs 7 pounds, which is non-refundable.

In today's Sunday Times there is a column by their financial trouble shooter/'consumer champion' -- Not sure if it is behind a pay wall but here is the link https://www.thetimes.co.uk/article/t...sley-8j3q7ltpv

The gist is that TFL has IT issues with double charging ApplePay and Chase issued credit cards (and apparently a few others). The 'consumer champion' offers this recommendation:

"The easiest way to avoid this problem is to use an Oyster card — the payment method sold by TfL."

And closes with this, which is fine for UK residents but likely irrelevant for visitors from overseas:

"If you prefer the ease of using your mobile, smart watch or bank card to pay, then registering your payment method with TfL will make it easier and quicker to correct overpayments. Customers can register for an online account at contactless.tfl.gov.uk. Customers using a Chase card and wishing to register will need to log into their Chase app, locate a “TfL — Transport for London” transaction record, scroll to the bottom and click on “adding your card to TfL” to get the unique card details to allow TfL to share journey history and complete refunds."
