unhappy client & poor customer service

I recently got my house keys at Royal cradle and 2 days thereafter I spotted some issues which was omitted on the day of Inspection. I Immediately lodged a complaint online with photos attached after struggling a few times with their website. I must say there is no sense of urgency with Cosmo as up to now there has been no acknowledgment or assistance on the issues mentioned on the complaint lodged, of which the major concern is my gate which imposes as a security risk. so much for a "world class" development.
