I'm sorry for the issues you've had with your cashback. While we can see a promotion code has been applied to the account, we're unable to track what this promotion code includes. Therefore in order to get some clarification and resolve your query, I can see we've raised this off to the relevant department for answers. As soon as we've heard back we'll update you via the support ticket that is currently open on the account.
I do apologise for any inconvenience this is causing and I'd hope we're able to resolve this for you as quickly as possible
