Useless customer service, couldn't care less.

Truly shoddy customer service! Placed an online order on the 20th Jan (7 business days ago!). Sent an email yesterday to ask what is happening with my order (yes! the customer needs to chase them up!) Received a phone call today informing me that they've just realised they don't have stock, would I like them to phone their supplier to find out if they can get stock - um, yes I want you to do your job and get stock of the products I have ordered and paid for. Why do you need to get your customers' permission to order stock of a product the customer has paid for??? They'll find out and phone back. I wait, I wait, and I wait some more... I phone back (yes! the customer needs to chase them up!) Oh no, we'll be getting stock by the latest Friday (10 business days after the order was placed! That is, according to their website, the longest you should wait for delivery! Not how long you should wait for them to get the product to their warehouse) The kicker? The agent on the phone tells me I can't expect anything better from them - apparently their website says that you can wait longer if they need to get mattresses manufactured. The website says this information is available under the "additional information" for the specific mattress ordered. Guess what, the mattress I ordered says nothing of the sort (I have checked. I have asked others to check. My order does NOT say it will be delayed at all). The agent's "so there" attitude is complete and utter nonsense! How does a company ignore a stock issue for 7 business days after a customer has placed an order? How do you need customer approval for getting stock in for a product they paid for? How do you tell a customer you will phone back, and not do so? How do you tell a customer that it is what it is and they must deal with it? So I will now be moving without the bed and the various other furniture items I ordered from Decofurn (an order worth nearly R11000 - apparently an absolute joke to Decofurn). Moving wasn't stressful enough as it was, so thanks for the totally useless customer service that has me even more stressed than before!
