Can I please get help on the problem because I can't be sitting with the problem and continue to pay

On the 2nd July 2026, after receiving a High Bill, I callled 2 Plumbers Moday & Friday who both found that there's nothing wrong in my Premise. I then decided to go to Hamberg Water Depot where I logged a fault with a lady called Salamina, she sent Technicians who came late at night and they didn't even bother to call and explained to me what they found. The problem continued and I then logged in a fault using the *** & they came and did nothing. I then went back to them & Livuyani logged a fault again for me. Technicians came and i explained to them my experience, they told me that they will do the test in the morning because it was already late. They never came until i decide to log another fault which they sent a very rude Technician with his Team & he didn't even listen to what i had to say & just left. Water is leaking even if the meter is closed because I did the test over night & checked in the morning. I have been logging fault with them but to no avail. I really need this to be sorted out and need some help.
