MIslead and poor service

am more than upset by the service that was rendered at the Joshua Door Kimberly.I made a lay-be with them and when I went to pay the balance and take my staff ,I was told they don't have stock.The sales consultant told me it was sold to someone else (like really now).All this time they new the stock was not there but they didn't border to inform me.Even before making a lay-be it was never brought to my attention that if a cash customer comes first they sell the stock,hence I'm saying I was mislead.I logged a complaints with their head office ,it been 2 Weeks and no one is attending to my complain.Their store manager is the worst,she dropped a phone on me whilst speaking to her.The staff they just don't care if you need assistance they'll be sitting in groups chit chatting and drinking coffee, if not holding phones on their hands.I also thing their head office is also to blame because there are no actions taken against employees@ Kimberly branch yet they always get complains.It's your duty to make me happy as your client and there is only one way to do it---- JOSHUA DORE PLEASE DELIVER MY STOCK AS PROMISED! AND KIMBERLY MANAGER YOU OWE ME AN APOLOGY.
