failure to deliver my couch.

I bought a couch in Boksburg and they didn't have stock because i was looking for that couch and they didn't have stock they borrowed me a couch from their warehouse. they came to deliver in December and due to the gate issues we had at the complex i reside in i requested the driver to come back at 16h00 as it will be sorted by that time. i followed up with the sales consultant about the driver she had no idea that they didn't deliver and did another follow-up i was told they don't have stock now. i followed up in January but i have been taken from pillar to post about them coming to replace the couch the borrowed me from November till today i have not received my couch.
