1 appears to correct. You can cancel any time and you will continue to get the cards that were paid for.
2 is wrong, the free tickets are ONLY given once per membership type.
So if you sign up for 1 month and get two free tickets... you do not get those free tickets ever again. If it re-bills you do not get them. If you cancel and subscribe you do not get them. If you can cancel and get a different length subscription, say 6 months you do get the 10 free tickets. Again, only the once, not on re-bill and not if you cancel and join again.
That said, the response indicates that you might catch the help desk on a good day and they may give you tickets as a gesture of good will. I would say, don't rely on this!
By far the cheapest way is 6 months at a time. You might consider a month to 'test' it and then change to 6 months. 12 free tickets.
