Need my refund

I bouht a bed last year October and within a month the mattress started to make noise and it states to flatten on both sides and the my sleep was no longer comfortable at all. I called the branch to lodge a complaint but the service that I got was very poor I'm the one who was busy calling them and they will say they will call me back and they never did. I continue to call them until they lodge a complaint into their supplier. It tooke a while before the mattress was change. I tried to call wharehouse to ask about when will my mattress be delivered and I was told that they did call at BedZone at Canival Mall and they were told that I am sorted which was not true, but they ended up delivering the bed in December. This Year May I lodge a complaint again this time it was not only mattress but it was base and mattress still im the one who was busy doing follow ups , finaly they called me at seal and they sent me a person who was going to do physical assessment and they confirmed that both base and mattress are not in a good condition and I have to go back to were I bough the bed and make arrangements with them. I went to the shop and I told them that I no longer wat anything to do with their beds because I do not trust them anymore.

They said that they will cancel the the contract and come to collect the bed but till to day they never come. I am so dissapointed with them because they told me that they will not refund me my money meaning I'm the one who lost not them because I already paid them +_R5000.00. Please help me to get my money back and they take their bed back
