I buy a new dji phantom 3 with an extra battery and one of the batteries gives me out an invalid battery error. I contact dji support and they do not reply. The battery was new out of the box. where is the costumer support? Are they waiting for the warranty to end so they can tell me to buy a new one ? Like ive seen in another post? What a disgraceful post sales support, ive had difficulties in my video work because of this.
