T. stirmi (purchased as female)

A young T. stirmi (1.7 inch body) I'm having trouble with, as it was purchased as a female, but one of my friends recently stated it's, in fact, a male.
Any help from professionals here? It's eaten a huge meal just two days ago so it's QUITE plump in these pictures.
I think you got what you ordered - seems like a female. Males will have a very dark triangle shaped patch of epiandrous fusillae just above the furrow which can usually be seen pretty early on. See an example here:

At that point you're literally my last hope as everyone else I've so far contacted keeps saying it's a male and I'm on my edge as I've spent a lot of money on this '100% female'.
Here's another two from today.
 
I would also say having owned many Theraphosa species that defo looks female .The furrow is all an even colouration at this size it'd be a blatantly obvious male.
