Vodacom Insurance declining valid claim

My daughters device was submitted for repairs a week ago, due to the tablet just not going on anymore after we charged it, it was assessed and concluded that its beyond economic repairs, and i was going to get a replacement device with the value of the insured. Today I'm told my claim is declined because its not accidental, although this device has been repaired twice because of falling and cracked screens. this warrants an acceptance for the device, as I have been paying monthly premiums to get a piece of mind and a working device. i cannot accept that the device could not switch on on its own, that only indicates damages to the device. I have spoken to Laurene and Barbra from the client services.
