Horrible service from Ok Furniture East London Oxford Street

I bought couches at Ok Furniture East London Oxford Street. I bought the couches for R15000.00 on the 13th September 2018. The store promised to deliver the following week to Queenstown because they did not have the transport that time . As we speak, 2 months later I have not received the couches. The store does not phone or send communication to let me know what is happening. I have been to the store numerous times and all they say is there is no stock. I called them and they said they delivered the couches at the Queenstown store. On the 26 of September I went to the Queenstown store and no one knew anything about the couches. Queenstown stored tried to assist by giving me torn couches which I could not accept. I can not pay R15000.00 for torn couches. I then went back to the East London oxford street and the manager did not care about assisting me, she was rude and kept on referring to me as "nana" which is very much inappropriate. Again I kept on following up with the store manager. Now I am tired, all I want is my money and I keep hearing stories and that there is no cash in the store. no one calls me when there is cash . I called the store and spoke to Bongi to ask for my refund, she was so rude and inappropriate about it. I told her today I am picking up my refund and all she said is they don't have money. how is this my problem after two months of not getting what I paid for? this is not right. This is not how you treat a paying customer. I am so disgusted with their customer service. the staff there needs training on how to deal with customers.
