Hi Alastair,
She had a problem with her credit card so we weren't able to charge her. And at the time we haven't fully activated live chat feature on our website so she got frustrated for a while. And then we resolved the problem and shipped out her items but apparently she didn't come back and write anything else on review sites. We wish she did though; but her final thoughts was not this bad as compared to her initial comments here. We tried to reach out to her later on, we even responded to her review here, but could not get a response from her.
I hope this helps.
