Bad Service Delivery

Im am not happy with municipality the charging us exorbitant prices yet theres no service delivery, water always not the and they no longer post statements on time , when i made an enquiry they tell its not their fault not receiving statement an d they very quick to shut down services they are barely providing for us. this is not acceptable, i requested they email the statement they was still an excuse that they don't have that system always quick to shift the blame
