claim denied

i feel they are just not being reasonable with claims. how can their access of claims of accident be same as that of ****** items on the car. they say because i have already bought the battery for R1200 and my access is R1500 i saved 300 meantime i have other issues in the car that still needs to be fixed. I just feel its not fair as i had to wait on a call for so long until i called emergency service to replace my battery. only when i call after i send email they tell me its good i replaced it cos i cant get any refund. how does the access of R1500 justify the accident of a car still going through repairs and replacement of battery, cos they know on the size of my car there is no way they will ever be assisting as they know their access will always be more. what's the point of having insurance, or to even make it part of claims because to me common sense is how their have reasonable claim on window where is is a set fee for that. access of car involved in an accident can cost up to R40k and battery cost R1200 and their access is the same maybe am slow.
