What can I do? I sent the seller a list of what I was buying and my offer, she agreed that this was correct.
Now she says that one of the items isn't actually included even though, I had actually asked her twice in total if it was, with the list I thought being the clarification of this.
This item for me is a deal or no deal type thing and I wouldn't have bought the items if she had said it wasn't included in the first place. The seller is saying that she was agreeing with the price not the list. 
I have already paid by bank transfer and feel ripped off quite frankly, as I am not getting what I thought I paid for. Is there anything I can do?
I hope this makes sense?
