@home appalling and horrific customer service and poor delivery

I am appalled by the extremely poor customer service I am receiving from @Home / Foschini / TFG Group. I ordered a sofa on Black Friday Sales, which was R12 999,00. At first my payment didn't go through, I then phoned and the lady said I must try again as their system is a bit flaky, I then paid and did not receive an email, even though it said the payment was successful. I then queried this - but got no reply, 2 weeks later I phoned the customer service line and they told me they will get back to me, which did not happen. I then phoned again and again, after about a week, I was told that they ran out of stock and now I have to pay the full price of R19999,00 for the sofa and reorder it - which to me is so bad and false advertising on @homes behalf. I then ordered the sofa at R19999,00, then asked whether my sofa could be delivered, which I made about 50 phone calls for, @home took about 5 days to get back to me, after sending lots of emails and making lots of calls to them. Every time, the person on the end of the call centre line just said sorry I don't know, but it is on the way and we will let you know. It is now the 27th of December, I am still waiting. When I phone - none of 100 different people that do not have a clue whats going on in this business can help me. My order number is p ********** 76 - @home I would like for you to honour your prices and pay me back the R7000 I had to spend extra and also deliver this sofa to me for free - as this is the most DISGRACEFUL and DISGUSTING service I have ever received in retail and had to deal with to date. I have had loads of guests for Christmas with no sofa to sit on due to your pathetic service. I look Forward to receiving proper feedback, but unsure if @home even would care to give me the service I deserve as a customer.
