Upstair neighbore do not want to fix my ceiling after his radiator leak

[Elisa Lisa p]

Hi, is a condo that I owne, our ceiling is damaged by upstair unit radiator. 

HOA is involved and they reply to HOA request of fixing their radiator and reply to HOA email according to hoa, but when I write them to fix the damage of my ceiling they just do not reply to my email or txt or phone call.

And this is not first time that’s happening, in past 6 years there was two different damageme caused by them. They choose not reply and I just fixed myself is about $150 each time. But I am getting really annoyed by their attitude. What would you do in my shoes. Get attorney this time?

I am beyond frustrated at this point.

thank you all in advance
