PAY EXCESS TWICE,RIDICULOUS.NO FEEDBACK FROM ABSA

On the 23 July 2014,I contacted Absa as I had geyser problems. J D Reliable plumbers came out the 24 July 2014 and advised the geyser burst, they had to drain the water from the geyser as it was full, when they drained the water it leaked on the ceiling and damaged the walls, the contractor advised they will send some one to fix the damage caused by the water on completion of the job we had to pay an excess which was suppose to have been once off.2 days later I had not heard anything from Absa so I contacted them they assigned an assessor days later, and a contractor came out to do a quote I was advised I will have to pay a further excess for the damage on the walls and ceiling,I contacted Absa and they advised the damage was caused by the plumber so I would not have to pay.The contractor send me an sms stating he will come out on completion of the job I R500 excess will be required I once again contacted Absa and they advised the plumbers report indicated that there was damage however they could not furnish photos as the plumber did not take any. I disagree as when the plumber came out he took photos.CAN MY CLAIM BE FINALIZED,MY CEILING AND WALLS NEED TO BE REPAIRED. NOT PAYIN
