I thought the date must be wrong but your screenshot shows it was December 2023 when you made a purchase- surely you are not seriously chasing the non-delivery of a £3 item you bought a year and 4 months ago?

"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
