tele-checkin goofup

The sad service levels of Jet airways continues... Here is one more such experience: I had called Jet for tele-checkin, and requested a window seat. Since they offered only a non-reclining in the front of the aircraft, I told the agent to give me something way back, so that I could get in and out of the aircraft easily from the rear entrance. She assigned 30F to me, confirming that it is a reclining seat. However, to my horror, I found that the seat assigned was, indeed a non-reclining seat in the last row! I begged the attendants in the aircraft, but they won't do anything!
