Stay away from the Sandton Branch, selling stuff which they do not have-no refund

I bought a 48v charger for approximately R 800 from the Sandton branch online on 19 May 2025. After no response, 10 days later, they inform me on enquiry that they o not have stock, although they marketed the item online. And why not inform me when I placed the order? They just kept quiet. I requested a refund on 29 May, and after numerous emails, 5 weeks after I have paid, I have still not received any refund, only promises. Extremely unprofessional in their emails, with no name of who you are dealing with. I have bought more than R 100 000 worth of equipment from the other branches with fine service. Stay away from the Sandton branch.
