Doorwall leaks when it's raining heavy

[Kelly Holly]

Since 2012 when it rains hard my doorwall leaks around the wood framing and doorwall. Tried to get fixed, sent videos even let the maintenance use my hose/water to see where the issue is. 2017, maintenance came and caulked outside of building (these are stacked condos and I am on the bottom) after doing same tests 5 yrs earlier. A contractor from this maintenance crew told me that is how the water is getting through. I am getting letters from the association to replace my doorwall at my expense because of this issue. Shouldn't they be responsible to replace for their negligence? I am responsible for the inside of my unit NOT the outside. If there is an issue because of improper maintenance and they are concerned I feel they should pay not me! I pay my monthly dues on time and always. Any help would be appreciated because I feel I am being bullied!
