Geyser Claim

I lodge two claims for my geyser(solar panel)The first time the assessor came out and just fixed the relieve valve .Again it happen second assessor did the same.A week a go the same problem occurred where water was pouring out from pipe/valve that was fixed(solar panel) and i phoned ABSA insurance again and the assessor refused to fixed the geyser.Every second or third week during winter I had to phone insurance for a burst geyser and had to pay excess fees.I refuse to pay any further excess fees cause if the first assessor done a proper job I would not have had the same problem every month.I request that a new assessor come out and do a proper fix to my geyser.
