Poor service delivery

Hello peter,I joined successo insuarence on october last year then this january my vehicle got affected with hailstorm damage then i laid a claim with them on the 27th of january they adviced me to take my vehicle from dundee to newcastle for assessment on 31st january from there they just kept quite until i phoned them on 19 february for follow up they sad there are missing documents. I sent those documents they kept quite again until i phoned them on 27 february for another follow they sad the'll call me back but they didnt until i phoned them again on 15 march and they said the claim was approved last week they sent me a quote/authorisation on 16 march which am totally unhappy with it because its expensive and has expensive excess payment needed. They said my excess will be a R6 891. I failed to understand because hailstorm is natural disaster i haven't caused any accident and worse it has minor dents and far more expensive then the highest quote i got for myself through other registered panel beaters which is only R2 800 to fix my vehicle. I phoned them again telling them how unhappy am they said they'll call me back but they didn't. I am really not satisfied with their service delivery yet i am their reliable customer. They should give me options of quotations like any other insuarence companies.
