There is no public information on a specific "hdb comments kind 1k 28" as this isn't a regular HDB identifier. Even so, HDB supplies many channels for opinions. The principle strategy is throughout the "Compose to Us" e-suggestions form around the HDB website. This form allows you to post issues https://hdb-feedback-form-1k-2829630.shoutmyblog.com/36200524/hdb-feedback-form-1k-28
