Bad service

I had recently bought a car and MFC sold me a service plan with them Innovation Group. Took my car to VW and they did the service. When they had to claim from them, there was an issue with my policy. Apparently, policy was supposed to kick in at 150 000km whereas my car only had about 90 000km. since the service was sone i paid and said would claim from Innovation. Explained the situation and they saw the mistake and amended the policy then after I lodged a claim. They took forever but eventually they paid however it was a little under R1000 short and their explanation is that the dealer overcharged me as that was not the rate they use with the dealer. I explained that cannot be my issue as this was all caused by them since the issue was a mistake with the policy. The consultant escalated it to her mangers and took them some four months to reply saying they will look into it. As of today, I have sent numerous emails, and no one even cares to reply. The service from the mangers is absolute horrible. I can't take you two months to check in the system if it takes the claims consultant less than 2min to see what has transpired. Worst service ever.
