Never buy anything from this company!

On the 25/08/2019 we went to the Cielo store in Stoneridge Shopping Centre and chose the Astoria Couch (velvet charcoal) and paid the amount as per invoiced to us at the store. On the 29/08/2019 the couch was delivered. The order however was incomplete as it came without feet (only realised this the next day as the couch was in a box) I phoned the store on 30/08/2019 to inform them, they however informed me to send an email for the matter to be followed up on. Since then I have been in contact with serval customer care liaisons trying to sort this issue, told by the last customer liaison on 26/09/2019 that the legs have been booked and will be dispatched. On 03/10/2019 had to send a follow up email as yet no legs were received. Only to be informed today the 04/10/2019 by the Head of Department for Customer Services Marinette Gerber that we were invoiced the incorrect amount and was delivered the incorrect item (we paid for an armchair and not a couch). We now however have one of 3 choices- 1. either they collect couch and give us an armchair, 2. we pay in difference, or 3. they collect couch and we get full refund. This issue has been going on for over a month and I really don't see how it is my problem if you ***** up twice, once in store and then again at the warehouse. The service is absolutely shocking as it appears no one knows what is going on or what they are doing and I mean no one!!!!!!!!
