3 month battery replacement saga

My battery needed replacing after a LONG weekend of tow trucks Uber because of my dead battery. On 11 September 2017 I called liquid capital to understand if a new battery was covered in my service plan that I spent a fortune on when I bought my used Hyundai IX35 from Kia Edenvale. I was told that well after year of owning the vehicle, it was still registered in the original owners name and they couldn't help me or give me any further information without speaking to the owner. I then contacted the dealership who I bought the vehicle from, in this case Kia Edenvale. When speaking to Pieter the used car sales manager, he wasn't able to tell me anything either and I was told someone who could help me with my liquid capital service plan would contact me.. I needed to replace my battery urgently as I had already waited 2 hours with no one contacting me, so my kind neighbour helped me out, took me to Mirtrams, bought a new battery for R1475 and he fitted it for me. 2 days later after contacting Kia a number of times again, I received an email with the details of my cover with Liquid Capital and low and behold, my battery was covered. I went through the process of completing documents for my refund, only to find that a week later my claim was rejected as my battery was still covered by warranty and I should have taken it to an approved dealership to have it replaced.. this is the exact reason why I contacted liquid capital and Kia in the beginning, but no one was able to assist. I escalated the matter to Chaya Finger, one of the only reliable employees at Kia Edenvale, who tried to assist and requested I resend the refund claim. To my surprise again some time later, the claim is rejected yet again !!!!! ? it is now almost 3 months after replacing my battery and still no resolution. Empty promises of the dealer principal contacting me, a good will payment still outstanding of only 2/3 of what I had to pay, but if I had taken it to an approved repair centre, it would have cost Kia at least 3 times more. Why is service so shocking in this country? Is it because I am a woman dealing with car issues that are traditionally dealt with by men? I'd like to think not... Why when you threaten to take things further do people jump, then when you don't they slack off again. So I need to stand on my head til I'm blue in the face to get this resolved????
