Break TV Stand, Rusty hinges and no show

On 23 April 2015 Kgomon came to install a TV Stand, Cupboards and fix granite in our home. the stand and cupboards look good. However, while building the stand they broke one of the stand doors. They promised to come back to fix the stand. Two weeks later we released that the cupboard hinges were rusting. We alerted them and they promised to rectify that. It has been six months of numerous calls, sms, emals to Monale/Monare and their father but no response. Everytime you talk to them they promise to come and fix the stand but never keep their promise. It is regrettable that a black smme with so much talent has such poor customer service!
