Rozel Furniture review: Salesman attitude

Dear Potential Buyers, AVOID Rozel Furnishing - Sungai Kadut (also known as Warehouse 69) as much as you can. My story as follows...
Purchased furniture at showroom, paid in full (per their requirement).
3 days before delivery, I am told product material and color not available. Asked to come to showroom to replace.
I told - pls cancel order as the color/material we wanted not available any longer, beside the point the waste of full month waiting for delivery date.
Rude salesman told, you have chop and sign on invoice - order will not be cancel. Instead of negotiating for alternative, keep mentioning already chop sign on invoice and I have no choice but to just buy whatever that is available.
Not only that, the salesman has no sense of professionalism - told me to get my 'facts' right. Shouted to me. Said I have NO DIGNITY. Keep scaring me if I don't buy the alternative - it is my lost and said I can complaint wherever or whomever I want.
Salesman claim to be a senior person in the organisation - it is a pity!.
I found out the reason the salesman can do and say all the above is becuase that is the way the organisation is structured - just make the 'SALE', no concern about reputation or customer service. Let me explain...
During that time, I search multiple sites and got hold of some senior management names in the company. I called the warehouse/head office numbers and asked to verify that the person is there - they confirmed yes. I told I want to talk,
they said, the person is busy and will call back. No news from them. I called at least 10-12 times talking to different person who picked up the phone. No one got any senior person to call me back. I emailed to them 3 times, no response at all.
Bottom line, it is a BLACK HOLE - if you get your purchase all ok - then it is ok. But if there is a problem with the purchase (which can happen natually when we buy big value items) - then you are are on your own - there is no help.
Today I am living with furniture which is not of my choice and got delivered 3 months late! So, as I said, my only intend of writting this comment is, only shop from them when you have NO CHOICE (for whatever reason).
I wish everyone a pleasant shopping experience.
