Poor service

I submitted a building claim with outsurance my geyser burst, so they arranged for plumbers to come out and assess and upon arrival they established that the geyser must be replaced, but emphasized that the first amount payable is R2500 which i assumed was the excess the company the insurance appointed advised me that they wont do any work until i paid the R2500, i obliged and paid the R2500 of which the guys started to replace the geyser. Upon my arrival at home i went into the ceiling to inspect the geyser and also the workmanship upon my inspection i discovered the geyser was leaking on to the tray supposedly a (brand new geyser) i went outside and realized that the overflow pipe is dripping and has been dripping since yesterday i brought this under the attention of the company that was appointed by the insurance and they advised me that the manufacturer of the geyser must contact me im very disturbed with this and i also brought this to the attention of the insurance cause now i will be having a water bill for that overflow pipe that's going to be leaking whole night again tonight, i thought the purpose of insurance is to put you back to the position of which you were before any incident but im far worse of now.
