Bradlows refusing to give me an item I paid for

I bought a bed together with a matrass protector at the end of June at their Atlantis store. They promised to deliver on a certain day and they did not, this went on for a week and I only received my bed the following week, I was not mad or anything, I understood. The bed came and it had some tears on it, unfortunately I did not get time to complain about this, July was my most busy month and it just gell inbetween the cracks. When they delievered the bed, they forgot the mattress protector and one of their store workers sent me a message on WhatsApp saying I must come and collect it, I have proof. I could not go at that period because I was quite busy and when I eventually went, apparently all the previous staff was not working there. I told the new employees of this situation and they could not help me on the day. I returned again and they scribbled something and said they qould follow up, they did not. I went again and they promised they would follow up because there qas np extra stock pf mattrass protectors so they don't know whete it is. But they will follow up . I went again and well, another excuse. My problem is that I am paying for something I DO NOT HAVE! I am sick and tired of going back and forth for a matrass protector, they are not even trying to help me. I am not purchasing anything there again and I would not recommend Bradlows to anyone else.
