It could be a small claims court matter if they were in the same state.

It's cheaper to write-off the matter as a learning experience.

Voro Motors. They're a fly-by-night operation like the other Kaabo dealers I found in the US. Ship from China and expect no support or warranty.

Also, no e-scooter shops will touch Kaabos because they're not designed for repair and parts are difficult to source. The wiring inside looks like spaghetti with random colors that don't match their wiring diagram and wires that go nowhere. In addition, the early model forks would break spontaneously due to manufacturing defects that lead to a number of grotesque injuries and perhaps a death or two.

PS: BBB is itself a widely-held misconception and fraud, perhaps the inverse of Yelp. It's mostly a feel good badge businesses pay for. Any business can join it and they have little incentive to police their "members" because, like binding arbitration, the "members" are the customers, not retailer's customers.
