Finrite insurance is a ****

I took my device for repairing and they sent me the amount of money i should pay, didn't make sense that the email says i must pay R1200 but when i called to confirm they told me its a mistake i must pay R800 where by the first time i payed less money with same problem. i asked them to take pictures of what is damaging my device since it is second time i'm fixing the screen with same problem (bleeding from the inside) but they keep cutting the call or putting me on hold every time i ask for proof of what is damaged inside. now i asked for my device back not fixed but they dont want to send it back. i keep calling and told it has been delivered but when i get to the store it is not there.
