Wal-Mart/ Product care plan

Purchased TV and 2yr service plan 7/29/2007. on 12/20/2008 the TV quit. I called the product care plan 24 hr service phone # listed & was told I would get a call from the repair service in a day or two. since I had not heard any thing yet, on 12/22/08 I called again only to find out my first call had not been acted on. They even had my address as Bosie, Idaho.(never been there) I then received a call on 12/23/08 that a repairman would be there the following Wed. in the A.M

(12/24/08) but none showed up. I called again that late afternoon to find out the service call was scheduled for Wed. the 31st of Dec. and I would receive a call to set up an appointment time. The repairman called that morning to let us know he would be here in 15 min.(NICE NOTICE) The repairman told us the "power supply" was bad but he would have to order it and he would be back the following week to intall it. Today is Jan 19th and still without a TV. Wal-Mart is good at giving the run-around.
