Bad Customer Service

It's amazing how Absa's people/contractors messed up inside my bathroom and now I get told it's my fault, it's OLD DAMAGES. How in hell's sake is it old damages when THERE Leak detector guy came out, THERE contractor fixed my geyser and wall and NOW WHEN THE GEYSER GETS REPLACED THERE CONTRACTOR SAYS IT'S OLD DAMAGES DON'T GET IT FIXED???????? So now I ask why didn't the leak detector people say there was a leak in the pipe as it's the job to detect these things, the guy who fixed the wall could he not have picked anything up. Now I have to be fixing all this by myself yet I pay for this service.
