Lack of feedback , bad service and Out of Stock

Purchased a lounge suite from Morkels Chatsworth. Deposit of R500 was paid on the 03.01.2016 to secure the lounge suite, balance of R8500 was paid on the 10.01.2016. We advised Morkels that the delivery fee of R650 will be paid on the 16.01.2016(Morning). Upon requesting for delivery for the 16.01,we were advised by Morkels that they will try to deliver on Friday/Saturday, and could not promise as a stock take was taking place. Numerous calls were made on Friday & Saturday and at no point was I was advised that there was no stock. Numerous calls were made on Monday to the sales guy & messages left & no response was received. Spoke to the Admin Manager and Branch Manager on Monday & was advised that they were out of stock, prior to this I was not advised of this at all.Throughout Monday & Tuesday the B/M was in contact with me and advised that she could not give me an answer as she was awaiting feedback from the warehouse - alarming that it takes a warehouse 2 full days to know what is going on with their stock. I was advised on Tuesday afternoon that delivery will be done on the 20.01. I have made easily over 20 calls to the warehouse, still no delivery
