LIFE PUZZLE "The door knockers" Can you help solve the problem ?

Here I have a real life puzzle.
Imagine that there is two door knockers.
One does not tell the truth and is truly bad and evil.Let's say we call him ONE.
The other is knoble and all in all good.I think We will call him TWO.
Let's also say that I can not tell ONE from TWO as they both look the same and I never get to see them at the same time.
When I ask one of them to fix the door, The door does not get fixed but becomes much worse. Now the door does not open at all.
I thought that I had asked TWO to fix the door but now I know that I had asked ONE.
My question is How do I get my door fixed ?

Remember that there is only ONE and TWO and that there is no money to call in a worker to fix the door.
Is there a way to tell ONE from TWO ?
Will my door ever get fixed ?

As you can tell This is a complicated problem and I need your help to solve it.
Please leave me your advice.
