This is just a heads-up for everybody to take a hard look at their credit card statements.
It may be a coincidence, but somebody used my credit card during the weekend to purchase an account with LiveChat http://www.livechatinc.com/
which is a chat application for websites.
I discovered the charge within a couple of days, and the company immediately refunded the $367 without any question but they are refusing to give me any information as to who this might be, other than to say it was "someone else", not me.
I've never heard of this outfit before, I can't conceive of any case where I would have been interested in a non-open source solution, and even if I had ever checked them out their free trial doesn't need a credit card, so they would not have had my number anyway.
I'm really angry that they won't give any more information, as now that leaves everybody I've been in contact with or worked with who could have gotten their hands on my card under suspicion, and of course the timing couldn't have been worse if it is just a coincidence.
