I have twice been let down by this company and had one good experience. I flew all the way from Sydney to Madrid (at great expense of time and money) on the basis that I had purchased a ticket through Football Ticket Net. On arrival they informed me there was no ticket. The money was refunded but the promised compensation has never been paid.
For a different game, at Wembley, I was told to meet someone at the stadium - they arrived late and the "ticket" had already been used so I could not get in. These are "once in a lifetime memories" destroyed by unreliability, delayed delivery and promising things they don't have. Even my good experience (Istanbul derby) was nerve wracking as the ticket was only delivered on the day of the match and I had no idea if it would arrive.
