I ordered a go cart from ATV discounter in December. My daughter rode the go cart for about 15 minutes before the front end broke. I sent the part back under warranty before January and since then have been working with the parts and shipping department more specifically a lady named Patti. Typically I am put on hold for up to 20 minutes or someone else picks up and tells me Patti has gotten busy and will call me back. This has yet to happen. I understand that the parts channel from China is unreliable, but most times when I call whoever is working tells me that they do not have any record of my order and I have to talk to Patti, then the cycle repeats itself. I asked Patti who her boss was and she said she did not have one, that she is the top of the chain. I am possibly getting re deployed to Iraq so I drove to Fort Worth to ensure that I got my daughters part before I left the country. The parts manager (Rob Groves) told me he would sort it out and get right back to me. I have not heard from him since. I got Blen Barlings email contact information from an outside sales rep. He emailed me that he would take care of this. That was the last time that I heard from him. The phone lines that they use are not working half of the time. I wish that I had found this forum before I bought the Go Kart. I am sure that other people have had the same experience. La Caveat Emptor.
