my understanding is, once you pay off your PSLs and you DO NOT purchase the tickets, you lose your PSLs. If you don`t want to be a sth anymore, pay off the psl and just walk away. You are under no obligation to buy tickets once the PSL obligation is paid in full.
Correct me if I`m wrong anyone because I`m not 100% sure on how the PSL crap goes. That was another reason I didn`t buy any seats that had a PSL on it.
