How do I contact a seller with a question about a Dyson battery

[huntervalley1991]

I have a question about a Dyson battery for a cordless vacuum cleaner.

Seller is in China and three out of four of their negs from this month alone are for selling shoddy batteries

There will also be no warranty, no matter what their ad says

I hope it is not a question because you have already purchased from them
