My invoice was very juvenile and had no number on it. I called them(House of Computers) back and told them the DVD drive did not fit my computer. They wanted to argue with me and tell me that it was the right drive for my laptop. I finally got a return authorization number, and sent the drive back that day. Out of my original $95.79, they were going to credit my account with $57 and change. That was last week! I sent it Express Mail on Monday, the 28th of January. I called them just now, at 5:21 PM EST, Febuary the 7th, and was told they had no record of doing any business with me. Should I have suspected a rip off when there was no number on the packing list/invoice? So far, I'm out over a $100, counting the mailing cost, and I still have no DVD drive for my laptop. So much for a bargain!
