My leaking faucet

My faucet has been leaking for over three years. Whenever I call landlord's office I am being told that the issue will be addressed. The plumber came twice last year and tightened the faucet promising to get the part and return in a couple of days. He never returned and I keep calling the office. It must have been a river of water that's been wasted here not to mention the energy since it is the hot water valve.
