Sold an old bed

About 4 months ago my mother and I bought 2 beds from Lewis in Middelburg but mine was delivered by Lewis Pritchard Street JHB, manager Mike. My mother then came and visited me for 2 month and when she returned home she realized that her bed felt different from mine true to a complaint I layed with her prior. Lewis Middelburg has been trying to assist but they are not getting assistance from JHB and now, even worse, we have to deal with their supplier(Bravo Brands) ourselves. I must say people at Bravo brands all have stinking attitudes, Christine says I as a 36 year old was jumping on the bed, a receptionist at the supplier's Head office hung-up on me and never took my calls again. I need the old bed sold to me by Lewis exchanged ASAP.
