Review on DJI Mavic Charger Black CP PT 000562 by Jared Gopalan

How a novice drone pilot bought this 'old' Mavic Pro charger based on comments that it fit the Mavic 2 Pro in preparation for a trip. The trip was unsuccessful because it didn't fit. When I asked for a refund the window had closed. The seller is unwilling to accept a return/credit for an unused/unused charger for a correct charger even after I have offered to pay shipping both ways. It doesn't seem to be a disadvantage for them; why punish your customers extra. new to sport and your business?
