Agree with D-Legend service, I m once of the victim, the sales person not the fault but the contractor, but now the sales person going bad attitude and give for higher price compare others, and with gangster face.
as my bad experience is air con installation. they give to sub-con to install, same story as above, confirm the date and time, end up din come, postpone and postpone,still ignore. WTF. end up come. with 2 stupid contractor, rushing ,simply drill without asking where is the place to install. break my wall with huge hole,simpply install and cabut. the hole simply put the white cement cover. now, in here, we should raise out and boikot dlegend let them close the shop
