Howler cancels tickets after they've been bought and paid for

I recently made the mistake of buying a ticket from Howler, for an event in November. I paid for the ticket. They sent it to me. So far, so good. Then they sent me a complimentary ticket, with no explanation. Not a replacement. It stated clearly that it was complimentary. I thought, great, and invited my girlfriend to the event. I even booked accommodation, at huge expense, now that we were both going. Then, Howler decided to cancel my original ticket. ***? So now I have paid for a ticket that has been cancelled for no apparent reason, I have incurred a huge accommodation expense, and one of us won't be able to attend? Unless we spend even more money and buy another ticket? Is this how Howler pushes sales numbers, ******ing money from the public? Do yourself a favour and don't pay any money to these people.
