Bad Bad service

I bought a Leather lounge set in February from Joshua Door Mosselbay, after a month the three seater started cracking. In March I lock a call to inform them about the problem. After numerous calls they collected the set only the 10 September 2015, clearly stating that the repair will be no longer than a month. After a month with no feedback I phoned and they told me that nothing has been done to the set, it is only standing in the wearhhouse in PE. After now more than a weeks phone calls to the branch the call centres, head office, still no feedback from head office. I am paying for a set I don't even have, the wearhouse said that if they get the go ahead to repair the set it will take 4 weeks for the leather to be ordered and then still it must be repaired. This is totally unacceptable and the worst service I ever had. The branch only stating that they are waiting for head office, and that I must then report them to who ever I like. This is going on now for almost 8 months.
