Russell's furniture not delivering.

I made a lay-bye at Russell's Alberton branch in March, I continued making payments via EFT during lockdown. I was so happy to hear that the store is opened for business I then made a final payment on the 21st of May 2020 I even paid for delivery. I was told that head office will call me to arrange the delivery of my 3 seater Aldo couch. 8 days later no couch has been delivered and when I called the store I was told by Rebecca that there warehouse does not have my couch, however she will keep me posted. I called today again at 12:05 the story changed and the same Rebecca said I she will update me. I just called again now Rebecca is not in the store now i need to start all over again and tell a new person my story. Their customer service is really bad. I need my COUCHE delivered either today or 31st of May 2020. THAT COUCHE HAS BEEN PAID IN FULL.
