Auto-One Car Care and Service

I bought a mobility scooter from them with a warranty in March . It broke down about 2 weeks ago and I brought it back for repairs . They told me it was fixed but when I tried to drive it away it went 3 feet and stopped again . I came home and waited for a week for an update and they said it still doesn't work but they didn't bother to tell me that I had to call them . I went to get it yesterday and asked what it was that they checked he told me they didn't check anything because the problem with electric vehicles is it could be a million things . Does anyone know where I can take my scooter for repairs because nobody at auto one is qualified ?
