Decofurn query bad experience

Ive bought furniture at decofurn and as they delivered my items, 1 of their item was damaged and logged complaint.. They confirmed to replace me after ive sent all documents they asked for including picture. But they blocked me and my wife on their facebook page to share our experience and is close to month now waiting for item. I cant even place my furniture since.. They always telling me they escalated matter to reginal manager but they waiting for feedback from them.. They promised me to replace but they not considering my query seriously... Staff being bored when you call in to get their manager..
