ABSA vehicle warranty claim nothing but a ****!

I bought a extended warranty for my vehicle with ABSA underwritten by the Innovation group. In October my car's engine light came on and it was losing power, I then took my car to Toyota to have a look. The claim was sent to ABSA/Innovation Group in November and each time I follow up I am not getting a clear answers to my questions. Each time I have to call in and push the agents to follow up and do their jobs. At no instance did one agent call me back with feedback even though I was calling in daily since the Late October till to date. Where can I lodge a complaint and force the ****** from Absa/Innovation Cartel group to pay as per our contract? They manipulate the Rand and manipulate services they are supposed to render!
