Service desk
What to quote, what to include, and what the desk can and cannot do for you. Contact routing is configured by the bank at deployment.
Quote your reference
Every state the platform can put you in issues a reference, and every one of them resolves to a server-side diagnostic. Quoting it is faster than describing what happened, and it is the only way the desk can see the detail that is deliberately not shown on screen.
What to include
The reference, the role you were acting as, roughly when it happened, and what you were trying to do. You do not need to reproduce the problem first — the audit trail already holds the sequence, and a second attempt on a cheque screen is not always safe to make.
What the desk can do
What the desk cannot do
These are not service levels — they are structural, and no escalation changes them.

Routing is bank-specific and configured at deployment.
