Bad service

I bought an inverter from Takealot only to find out that the inverter does not work like a generator, and our primary concern was a backup system for the gate motor and alarm, but this inverter couldn't be plugged in, and replace the main switch l tried to return it However, their system did not allow me to return it, so I sent it to them, and they were unable to assist me sending me from pillar to post The supplier informed me that TakeaLot is the only company that returns products.
