We may refuse to pay a transaction:
• If we are concerned about the security of your card or account or we suspect your card or account is being used in an unauthorised or fraudulent manner; or
• If enough funds are not held on your account at the time of a transaction to cover the amount of the transaction and any applicable fees; or
• If there is a negative balance on your account; or
• Because of errors, failures (whether mechanical or otherwise) or refusal to process a transaction by merchants, payment processors or payment schemes.
If we refuse a transaction, we will inform you immediately, if we can, unless it would be unlawful for us to do so. You may correct any information we hold that may have caused us to refuse a transaction by contacting Customer Support: email firstname.lastname@example.org or call +44 (0) 2080 368814.
