These guys take your money as soon as you make a purchase and then send you an email saying that the reservation is "pending" and you should call. Then when you call, they lie and say that the prices changed while you were filling it out. The new price is (surprise!) much higher. When you try to cancel it, they try to charge you an insanely high cancellation fee. But what are you cancelling? If the prices changed, and no ticket can be bought, what is there to cancel? They also get extremely aggressive and try to force you to pay.
A big thing to note is that they are using fake names and imagine people are too stupid to notice. This place should have been shut down ages ago.
