No support contact for Purchased goods

I purchased a battery Narada 48v 100ah lithium battery from Takealot and now i have a problem that requires technical support and I can't get it because takealot on their documents said it was sold by Nexnovo which appears to be a company in Lagos that uses a financial company's number in south Africa which really got me worried as to why and who will provide support, the Takealot website doesn't give you a number to call instead i got a number through another source to try and call and no answer after an answering machines took the call. i paid R28000.00 to get this pathetic experience. i need someone to call me urgently i even tried to reach out to Kim Reid

My solar system is down and i need urgent support *** Griffiths
