Sealy matress saggingwith no response from Manager

I bought a Sealy bed from Russels in 2012 and it started sagging. I called the Sasolburg Johua Doore and spoke Leon to sort it out. First he logged a call for the wrong beds and after I called Sealy factory myself he logged the complaint for the right bed. This was 3 months ago. Sealy informed me that I have to pay a warranty fee of which I did 2 weeks ago. Sealy informed me that the exchange was approved and I need to communicate with the Sasolburg branch to get my bed exchanged. So I did. Leon said that he will need to find out if there is stock. That was the last I heard from him 2 weeks ago. I called their head office on 10 July 2015 and they said someone will call me back within 24h. No one did. This is poor and really disgusting service as I had to call between branches, suppliers and head offices to try to sort it out myself.<br> I am now fed up...
