Query: Discount DLP TV Lamp Purchased

The replacement lamp I purchased from Discount DLP burned out within one week. I contacted the company and heard nothing back from them. I sent them the burned out lamp along with a written letter. They ignored my email and letters. I never heard anything back from this company. The lamp was not cheap - they charged $107. and $35 for shipping. After they failed to respond to any of my inquiries I ended up having to going directly to Sony to get a replacement lamp.
