Russels does not deliver

My mom purchased a fridge from Russels, Chatsworth on 28 December 2015. She has not received delivery yet. Everytime we contact the store, we're told that they have implemented a new process and that the head-office is handling it. The staff at the Chatsworth branch is arrogant and did not give me a chance to get a word in edge-wise. The salesperson is rude and not helpful. I then contacted the head-office. I was put on hold and then transferred to extension 0000, which rendered a message of \cannot be transferred"and the call was discontinued. This type of service is absolutely poor. It seems like these companies will take your money and then not deliver. Their staff will not even help. When I spoke to the branch manager at the Chatsworth branch"
