Purchased a brand new scooter, was missing pieces. Strung along, promised a part, and lied to for over a month. We purchased a TaoTao ATM50-A1 model scooter. It arrived in decent time - roughly 10 days. After assembling, it was discovered there was a piece missing. A 6 month parts warranty was included, so we contacted the company via email - as there was no answer via phone. After no response for over a week - we opened a charge back with our bank, as we had a $700 product that was as useful as a paperweight. After opening the charge back, we were reached within 24 hours! The only way they agreed to help out was if we closed the charge back out -- with much hesitation, we did. From there, the responses of Chris M, were sporadic in response time anywhere from right away to days at a time. After waiting over a month - I contacted Tao Tao corporate in California - and after a bit of research on Tao Tao's end, the parts guy came back stating that the company was out of business and NOT an authorized dealer. Thank you to Josh at Tao Tao Inc in California for being so prompt and getting the missing part(s) out to us along with the missing registration papers. Proven Power Sports is not a reputable business, with HORRIBLE customer service and business ethic.
