Battling to get back money.

On 10 December 2017 I bought a lounge suite from the Krugersdorp branch which I paid in full. I was told that delivery takes seven working days. On the 20th of December the delivery team pitched up at my house, not only with the wrong lounge suite, but it was severely damaged. I showed them photos of the suite I purchased, and told them to take back the one they brought. They told me that I should get my lounge suite the following week, but it never happened. I phoned the Krugersdorp branch and I spoke to the manager who said he will phone head office and clear the matter. The following day I phoned him again and he said tthat he could not make contact with head office,upon which he gave me the number and asked me to try and make contact with them. I phoned head office but there was no answer. I thought that they might have closed for the festive season and decided to wait untill the 2nd of January and then phone again. Eventually someone answered the phone and said that she would look into the matter. A few days later I sent an e-mail to head office and asked if someone could help me get my lounge suite. When I got no response I phoned the manager at the Krugersdorp branch and I told him to cancell everything and pay back my money into my bank account. He asked me to bring my original receipt and ID book as well as my banking details. Because I was working, my wife took all the necessary documents to him and he said the money will be in my bank account within 24 hours. It is now five days later and still I don't have my money. Today I got hold of the lady who received the documentation from the manager from Krugersdorp, and she said that he did not follow procedure. I asked her what the procedure was and she said that his regional did not sign the forms. I asked if she could phone him and tell him what procedure he should follow. She agreed. A few hours later I phoned the manager at Krugersdorp again and asked him what the latest developement was. He said he had previously made refunds but it was never necessary for him to get a signature to be able to make a refund. What am I supposed to do now?
