Zen for Lifetimers generally comes 1 to 2 days after your anniversary date - the day you purchased the LTS. So if you bought yours on the 3rd you can usually expect the Zen any time between the 3rd and the 5th.
Of course the Zen gets deposited directly into your bank and does not show up under your Account balance. So if you don't look at your C-Store value of available Zen it's quite possible to get the Zen without even knowing you received it.
If you don't get your Zen you should file a Support Ticket and wait for a reply.
