No one answers the customer service number, so you have to leave a message. However, the message is returned relatively quickly (usually the same day). I had to order a replacement remote for my cart. The original remote is no longer manufactured so a replacement remote requires an upgrade kit. The upgrade kit costs $59 and the remote is $100. Seems a little steep for what you get. The YouTube video on the website for my cart shows a cart that is not the same cart, so instructions have to be in print form. The remote and upgrade kit came within 2 days which was quicker than expected, however the printed instructions were not included, so another call to customer service was required. Same story - leave a message and it was returned quickly. Then the instructions were emailed to me. When I went to install the upgrade kit, it was relatively simple, however, the instructions said the remoter should be paired, which it was not. There were instructions on how to pair the remote, but they were somewhat confusing. I left another message for customer service, which was returned quickly, but I had already figured out how to pair it. The instructions say to put the cart in "standby mode" (just plug in the battery). What I normally would do is push the battery button to stop the battery light from flashing. This did not work. The remote cannot be programmed unless the battery light is flashing. This should be noted in future instructions. However, Zach in customer service should be complemented for returning calls quickly and being a knowledgeable resource.
