Conair TAD-1220W Digital Answering Machine

I purchased the Conairphone TAD1220 on sale at Kmart for $9. It was easy to setup and worked great for 2 weeks. After missing some very important calls I discovered that the machine had stopped recording. It would answer, beep and pretend to record the message, but wouldn't.

Conair will replace the answering machine if I send it back with $9.50 shipping and handling (more than the purchase price). Unfortunately I didn't save the receipt.
