In reply to Cesar.
Hi Cesar,
We covered some possible avenues based on the level of escalation between homeowners and the MCST here: https://www.99.co/singapore/insider/resolve-dispute-condo-management-msct/
The advice is to mediate first, preferably through a neutral or third-party mediator. If the situation does not improve, even after 3rd-party mediation, you may also want to raise this with the Strata Titles Board, as suggested in the article.
