Worse service ever

On the 9th I was at nelspruit for my car service I'm currently with Innovation Group one of the service consultant she's an African lady she asked if I'm still with my service provider I agreed she called them as usual n gave them KM on my vehicle of which are wrong she gave rmthe 8550 of which my car as we speak is on 65500 they declined my claim I called the daughter with them although the problem was with the dealer I end led up paying cash for the service as the situation is like this who is supposed to refund me coz I'm not a faulty but the dealer is they failed me as their client n now I fought with wrong ppl for no reason I really need answers on this I need my money refunded to ne back
