Time Out not working - hosted Pay Option

It does not appear as if the 1 hour timeout is working for our hosted pay option, and it's causing a major problem for us.

Our hosted pay page: https://www3.moneris.com/HPPDP/index.php

 

- We reserve the tickets on our website for an hour and a half. After an hour and a half, if the purchase is not completed, the tickets become available again for someone else to purchase. This is under the assumption that the Moneris Page should time out after 1 hour.

 

The time out is not working after 1 hour. I did not complete the transaction for an hour and a half, and I was still able to submit a payment when the page should have timed out. The problem is, if a payment is submitted AFTER the tickets are no longer reserved, it causing an overbooking issue, which is a huge problem.

 

When I tested the time out about 2 weeks ago, it worked. It is not now.
