Help & support
We’ll try to resolve your issue as quickly as possible.
Once you’ve contacted us to raise a dispute, we'll either send you a letter or email confirming the outcome of our investigation.
The time it takes to resolve a dispute depends on how complex it is.
We can only start investigating once the transactions are fully processed.
If any disputed transactions are still pending, we need to wait for them to be fully processed before we can initiate a dispute on your behalf. It generally takes 3 to 5 business days to process a transaction, although it can take up to 10 business days.
Dispute investigations can take up to 21 days. We’ll contact you if the investigation is taking longer.
If your dispute is successful, your credit will appear as at the date the disputed transaction was processed. For example, if it was in pending and then processed on 5 February, your credit will appear as at 5 February, not the date you raised the dispute with us or the date your dispute was resolved.
