Supply of damaged goods and poor service

Bought couches at Thohoyandou House & Home and had to delivered in Middelburg Mpumalanga. So the Witbank House & Home delivered the couches. Firstly had to wait for more than 3 weeks for delivery of goods I bought cash, secondly when they delivered the set was not complete, thirdly they assembled the couches incorrectly had use faulty couches, fourthly had to beg them to return and come and fix the couches. they return but even after returning to fix my couches all they did was make it worse. Worst service I have ever had from a Furniture shop. Lastly they then deliver the other couches and still the other couches has factory faults.
