Maintenance Connection from Alberton and owner Sean Potgieter

Got hold of this company to do some waterproofing in my lounge, repaint and replace ceiling. The owner's name is Sean Potgieter. Then also install new ceiling in main bedroom. He quote me R18200. He needs 50% deposit which I paid. After 5 days he ask for further R5000. Then he never pitched up again. His staff is uneducated he left them here to do work after he promised me he will be on site full time. Now I want my money back and he refuses. It will cost me now even extra just to get somebody to come and fix his ******* .
