Faulty meter

Water bill shot up yo over R4500 end of last year with one person in the house . Reported to municipality and they advised to call out leakage detectors .... did everything and paid all for 3 call outs . Then they said we need to have the meter checked , paid the R933 22 nov . Said it would take 2-3 weeks . Called in December , they said nothing was actions because staff were on leave . Called , as advised on 29 Jan and still nothing has transpired and they cannot say why no action has been taken . In the mean time we have to pay the exorbitant amount every month .
