Appauling Customer Service

Just before Christmas my husband and I made a cash purchase for a Restonic Topaz Base Set which was delivered on 22/12/2015. About a week after that we called in stating that the mattress is making a metal noise. We were then told that someone will call us back which nobody has. We then called in again during the next week and spoke to the salesperson who then stated that the factory only opens 11/01/2016. During the week of the 11/01/2016 nobody got back to us and then i phoned in again at which point i was told we will received a call back. We did receive one call back and we again had to advise what the problem was. Since the week of the 11/01/2016 nobody got back to us and i called in again on Friday, 21/01/2016 and asked to speak to the manager, who i again had to explain what was wrong. I stated that either they collect their base set and give our money back in order for us to make a purchase somewhere else. The manager then took my number and stated that someone will call me back. Up until this hour we have heard nothing from anybody from the store. You have our cash now it is to hell with whatever issues you have with the product sold to you!
