Order/sales number

[Sarah0011]

Hi all, 

I have a claim with Topcashback for missing cashback. They are asking for an account/order/sale id beginning with N7", "N8" or "S0", but I could not find any.

Does anyone know where I can find it?

Moving this to the billing section where staff will reply (daytime, Monday to Friday), @Sarah0011.
