Question about Segway-Ninebot P65I

Now I have found out that the scooter has leakage current because the battery is always flat. It was picked up for repair and it should take 2 - 4 weeks, after 4 weeks I was put off, it still hasn't arrived - only after 6 weeks, Dhl drove around with it, after 8 weeks I asked again but now it has been at Galaxus for 14 days and I should ask again in 4 weeks. I will never buy anything here again. This is how they treat customers. I have now called in a lawyer. I cannot recommend it!!!
