Bad customer by sleepmasters Nelspruit

Last week Saturday I bought a bed set at Sleepmasters in Nelspruit.it was paid in cash and the delivery was set down for Monday, 10 February in my home at Barberton . On Monday I received a call from the sales agent apologizing that the bed that was supposed to be delivered is broken and that I will be advised when a delivery will be done..On Thursday I received an sms notification indicating that the delivery will be done on 15 February. On the 15th I received another sms informing me that the delivery will now be done on the 17th. No apology for the inconvenience. On the Saturday, 15 February another sms came through indicating that the delivery is now on its way I must stay put in order to receive the bed. My family and I had a family event to attend and so by afternoon I called the Nelspruit store and I found the most rude agent you can ever find. After telling me that I was not on the system she dropped the phone on my ears. I am so unhappy and angry. I have supported the shop by the sale. In return I get the worst service I ever encountered..I am now even considering cancelling the whole thing and demand my money back.
