Poor scratch and dent service

I have been with auto and general for more than 2 years, and i have never made any claims until the 13th on August when i get my scratch and dent, which i logged a claim on the 16th, and i was told my claim was rejected because they quote which they have made was above R3000, i must do my own Quotation which will amount to less than R6000, i made the Quotation, they called me we got cut off by network, i called them and they kept me on the line, which the guy who assisted me said they didn't receive my quotation, i must send it again, which i did, but up to today, no response... Thinking of cancelling the whole insurance because this show that they don't care about customers
