This might also be called a ‘customer number’.
You might have a separate reference number, for example, if you’ve already written to your supplier and they gave you a reference number in their reply.
For example, I think my electricity meter is faulty. Include details like dates or time frames if you know them. If there’s more than 1 problem, put them on different lines or in a numbered list.
If this is your first complaint, leave this blank.
For example ‘14 January 2022’. If you don’t know the exact date, try to be as specific as you can, for example, ‘January 2022’. If you have complained several times, list the dates.

For example ‘11 March 2022’.
