HDB varnished once for my parquet already coz there are footprints in MBR, and bad stains in BR2 . But I am not satisfied coz there is still a big patch of black stain on my BR2. Went to the site office last Sat and the sleepy lady said that they already did it once, they cannot do it again! I so unhappy and they ask me to look for their manager Mr Tan on weekdays office hours. Can anyone advise how to get them to varnish again or anyone already did revarnish more than 2 times by HDB? Should I go online to email, will that be better???
