Disgusting customer service and poor communication

So let me start by saying I can be very patient with staff and generally give people the benefit of the doubt.. But the treatment I received at Decofurn Milnerton is ridiculous. I purchased a couch end of July this year and ask them to deliver at the end of August as I was moving to a new place at this time. The couch I purchased was a two piece, it was the Gia lounge set that came with the ottoman. At the time of the purchase there was a sale and the 2 piece was just under R10 000.. Moving day came they delivered the main piece (the 'L' but not the ottoman) I was told they had no stock of the ottoman. So I asked how long does it take to get stock... Cause they had the full month of August to aquire the ottoman gosh it could have been made in that time. It only came at the end of September after countless calls and complaints... By the time it was available they wanted to charge me again for the ottoman and delivery.... I already paid for both and the ottoman was on a sale at the time of purchase... Apparently the delivery guy that dropped the first piece signed off the complete delivery and I wouldn't have received the ottoman unless I followed up.
