BAD SERVICE EVER!!!!!

I bought a corner couch on the 29 of March 2018 at Russells Silverton, i was promised delivery on the 3rd of April 2018. Waited the the whole day for nothing, i tried calling the store the following day and they didn’t pick up. On the 6th i called the store again and they told me that my couch was taken by another customer who had a laybuy on it and they promised to source another couch for me. The store doesn’t call me for updates but every time i call them i get a different story, I’m so disappointed with Russells. I bought the couch cos i don’t have one, now is 3 weeks and I’m still being **** to and still don’t have my couch. when i tell them i want my money back, I’m then required to follow the process and submit whole lot of documents which were never required when i bought the item. This has to be the worst service EVER!!!!!
