I have my sales receipt and I purchased my Compaq computer 5304 on 10/9/99 so you see I did get it within that date.I then called 1-877-266-6483 which is where I sent the rebate they told me the same thing over again and got smart with me which I was not happy about if they don't want to give out rebates they should not offer them.I then e-mailed Compaq Costomer Support on the computer they gave me another telephone mumber to call 1-800-322-9435 I then called them and they in return told me to call back the first number and they also got smart with me. I am writting to you because I am upset about the whole thing so please let me know if there is anything that I can do. Thank You Very Much. Bonnie Phillips
