Bad Service and getting rejects

I bought two king beds from homechoice, brand new beds but they didn't even look new. I called in and I spoke to the manager Anton and he told me that they can change my beds but now I have to pay an extra R4k which because I want proper beds I agreed that I will pay. I have been on Anton's case for the past 4 months now and he keeps telling my personal assistant that he will get back to us and he never does. The service is ridiculous and I’m at a point now that I actually want my money back and I am also not willing to pay an extra R4k anymore because I feel like it’s a *******. I mean I paid for the two beds and now for them to change their rejects I must pay more. I will post on all social media until this is resolved.
