Obligation of executive committee to address a written complaint

I am concerned about the delay in our executive committee's addressing a written complaint which I made in October. It is not on the agenda for our forthcoming meeting. We are owner/occupiers.

In September my husband had a heart attack during the night. I called OOO, but the ambos were delayed in getting to us because they took precious time working out how to access our building, which is one of a large complex, poorly signposted, & with an unlit  security panel at the door with instructions which are hard to follow.

Following this, on the advice of a committee member, I wrote to the committee with a list of suggestions for improving access. I was told these would be addressed. Nothing has happened 4 months later, not even getting it on the agenda.

I have discussed the matter with various neighbours, & found that others have had similar problems with 000 calls, & that there have been calls for the committee to act for at least 5 years.

Do the committee have an obligation to act on complaints, & to put residents' letters on the agenda?

Would there be a legal case against them, should someone come to harm because of their not having taken action?

PS: my husband survived, fortunately. Who knows what will happen to the next person?

Sincerely

Kate
