Terrible Service by Richards bay Toys R us ( selling second hand products )

On the 28.12.2023 i went to toys r us Richards bay to buy 2 Hoverboards for my daughters i paid R7399.80 for both only to get home and find that both of them are old with scratches and dirt and there are no chargers inside and the devices are not even coming on, i immediately had to take them back to the store and they could not find the chargers and the manager Paul did not even bother himself with attending me but sent a Junior staff who did not even know how to handle the situation but kept going back to him to find out what to do ( Paul was not doing anything at this moment ) i eventually confronted him for not attending my situations and showing no interest in me and not even apologizing to me for the inconvenience and the worse part is the situations could not be solved they could not find the chargers for the Demo Hoverboards they sold to me at full price and these devices were the last 2 on stock, eventually he tried calling around to get replacements to no avail so i asked for a refund which he then told me i would have to come and collect in cash the next day after they had made the money , i then refused and said if they cant send it electronically then he would have to go deposit that money into my bank account of which he refused and eventually called someone who said he could do an electronic credit via the till , we then proceeded to doing that on the 28.12.2023 but to date i have not received my refund if i call the store they keep telling me that he is not available. I cant even go and look for the hoverboards elsewhere because i have not received my refund and i am being deliberately ignore by this Richards bay store Manager by the Name of Paul : terrible ..terrible service.
