Terrible service Makro Centurion

I purchased an inverter from Makro and it has factory faults and issues since the first month of purchase the unit was booked in 4 times already and it has been over a month with absolutely no feedback, no communication from makro. The service at the centurion branch is absolutely terrible. every single time the unit has been booked in this is the same kind of experience, I need to drive back and forth for feedback.
