What may be happening is you try and chargeback multiple times, banks think this is unsual then run a fraud check - bot saying it is happening but 3 accounts being shut is a red flag and definitely worth getting a SAR in CIFAS to see what comes back.
Banks become aware of CIFAS markers when they are a member of CIFAS and conduct checks against the CIFAS National Fraud Database. These markers are placed on the database by member organizations when they suspect fraudulent activity or an unacceptable risk associated with a customer. When a bank member runs a check, the marker will appear, potentially leading to further scrutiny or even the rejection of an application.
Here's a more detailed explanation:
CIFAS is a database:
CIFAS (Credit Industry Fraud Avoidance System) is a not-for-profit organization that maintains a database of fraudulent activity and risk information related to financial services.
Markers are warnings:
CIFAS markers act as warnings to other member organizations about potential risks associated with a customer.
Banks are members:
Many banks and financial institutions are members of CIFAS and use the database to assess the risk of new customers or when processing applications for financial products.
How banks check:
When a bank member needs to assess the risk of a customer, they will run a check against the CIFAS database.
Marker visibility:
If a marker is present, it will be visible to the bank, potentially triggering further investigation or rejection of the application.
Not on all credit reports:
CIFAS markers are not typically displayed on standard credit reports generated by agencies like Experian or Equifax.
Victim markers are different:
Some CIFAS markers, like those related to being a victim of impersonation, are displayed on credit reports and remain for a period of 13 months.
Challenging a marker:
If you believe a CIFAS marker has been incorrectly applied, you can challenge it by submitting a Data Subject Access Request (DSAR) to CIFAS to understand the details of the marker and then potentially challenge the financial institution that placed it.
