Keyless Entry Remote Fob Clicker for 2002 Toyota 4Runner With Do-It-Yourself Programming

I received the remote from this company in a timely fashion. I followed the directions to program the remote to no avail. I actually tried to program the remote at least 5x and it still would not work. I had a 2nd remote from the manufacturer that was not purchased via this e-tailer and the directions worked for that remote. I contacted the company via email at least 5x. I got a reply indicating a return number and they said to send it back for an exchange. I did this but due to my own negligence of not sending it back with a tracking number, they claimed they never received it back. I emailed them at least 4x before they replied saying they received nothing back from me and I have never heard from them since. I would rate their customer service a ZERO as well as the product they sent me not working. I am out the money and the remote.
