The generator guys the wors company you can contact

I contacted them regarding my generator, they were quick to respond, a time was booked for them to come and the were a hour late. They identified and replaced the part at a cost of R2000 a couple of days later the part they supp**** stopped working. I contacted them again and asked him if any warranty was available the person said yes. I asked him when can they come and fix it under warranty, they do not respond back too my messages. They are ***** and they should close there doors.
