Poor after sales service-Incredible Gateway

Bought a DJI spark from the gateway branch. After 1 week, there was a software issue. Had to send it in for fixing due to this issue. 2 weeks later I had an issue with the camera. Sent it in again. I was called stating that there is physical damage to the product and I must pay R3000 ( The device was brand new and this was stated on the job card when bringing it in ). After back and forth emails., I am now being told some story of sand damage. This issue is going on for over 2 months now.Very poor service from a reputable company. This is very disappointing.
