Pinnafrica extended warranty

I have bought an extended warranty with Pinnafrica through Jeep Nelspruit. Recently my car had a challenge with cooling system and when I took it to the dealer it was then realised that the radiator was leaking. Pinnafrica demanded the pictures of the radiator of which the Dealer {Rola Jeep} provided them the pictures indicating the leak. Pinnafrica did not accept the pictures and they have demanded that the dealer must remove the radiator from the car and take pictures. And if they decide not to cover the repairs I must be liable for the stripping of the radiator. Jeep indicated that the pictures were clear enough to see the LEAK. Should pinnafrica requires the removal of the radiator they should authorize the repair because it is evident that the radiator is faulty. Justin from pinnafrica advised me to take the car to borsch. On my arrival at borsch we realized that they are just an insurance without account with Jeep or Borsch. At borsch they removed the bumper to access the radiator and took pictures and them to PINNAFRICA. But still they didn't accept the pictures and Justin told me that the radiator is leaking due to wear and tear and they are not going to cover anything. PINNAFRICA don't care about clients and it is difficult to deal with them. They have waisted two week of my time they knew that the problem was the radiator leak but they decided to send me up and down knowing that they are not going to cover my claim.
