100 Watt Waterproof LED Power Suppply for LED Strip Light Driver Transformer Ac 90-277 Volt to 24 Volt DC Output UL listed

I bought this product because it supposedly supported 277V input sources. The product in the picture shows it supports 277V, as does the product name and the the product description.Upon receiving it, however, it only supports 100 ~ 130VAC, which is useless to me. How can I return it?

Muy bueno
