Bad experience

I'm not happy with the service I received, I bought a cloud nine bed in March 2020. At first we had an agreement with the sales agent at the store they wanted to give old bed that they display with. I paid almost R10000 for that bed they didn't explain that they will deliver the cloud nine mattress but the base is not cloud nine base, now I'm having a problem with the base it has a funny sound, I called South Gate branch they said they will send someone that person said they can change thi base, my argument is that why this people didn't explain that I was paying R10000 mattress only it doesn't include the base, I'm not happy I fill like they ****** me. I can not pay so much money at the end of the day I'm not happy with the product. I'm going to put this on twitter so that everyone can see that cloud nine is not trustworthy. Can someone call me ***) or email me so that we can resolve this or can I have my money back
