Issues after busying a house from Engel & Völker

Hi Team, Recently I bought house from Engel & Völkers in Crescent wood country estate, Midrand. It is 4 units but registered as Free standings, We have issues with them from Day 1, Promises they made did not solve any of them. Jan-19 I have receive R 51500 invoice from Jwater, which includes 4 units water usage, JW identified that one water connection is given to all 4 units, later in Mar-19 these connections were properly connected to each unit. But E&V team failed and did not want to solve the issue with the water where now I am liable to pay the amount to JW. Last month JW took water connection for 1 week for my unit. This is the 2 nd time I am raising complaint on E&V on Hellopeter but nothing is moving. Team Can you please take necessary action / steps to get solve this issue.
