carpet maintenance

The carpets on the stairs of the common property in our 3 story block are  worn out with loose threads & no capping on the edges. Carpet app.30 yrs.old &  the dangerous state could cause someone to have a serious mishap. Replacement has been on the agenda of A.G.M for several years but despite the Strata Manager stressing the importance of replacement,,the Executive Committee refuses. As an absentee owner this distresses me greatly as I feel as well as being dangerous, it looks awful & devalues the property. Any suggestions as to what can be done to remedy the situation without causing  WW3?  hyacinth
