Rude store manager - Consumer Complaint for INCREDIBLE CONNECTION - HEAD OFFICE

On 2021/04/30 I bought a Connex tablet for my child at Incredible Connections Bloemfontein for her birthday. We opened the device on Monday 2021/05/03 and I created a email address for her but since she is under age I had to link her account to mine to give permission for her to download anything from Play Store . After doing that the tablet didn't want to download anything. So I asked my wife to gi back to the store to ask for assistance but she was told by the Technician to bring the tablet back home so that I could delete the account before he could help her. I did exactly what he asked and deleted the account. My wife then took the tablet back again but the problem persisted. On Saturday 2021/05/08 I went back to the store with the tablet. The Technician(Mohau) said he couldn't help me since the account still shows on the tablet. I told him that I deleted the account and even if you go into it, it shows that the account has been deleted.He then advised me to take the tablet to Procell so that they can restore the factory settings since they can't do it at the store. I then took his advice and went to Procell whereby I was helped to restore the factory settings but I got a bill of R250.I then went back to the store and showed the Technician the bill but he told me that what I did was for my own good since the problem was mine. I asked him who was going to refund me my money but he said the store can't refund me since I took the tablet to Procell. He even mentioned that what Procell is doing is even illegal and asked him why he would send me to do something illegal but he said it was for my own good since the tablet was mine. I then asked to see the Manager(Charles). He came but he had a bad attitude towards me telling me that he won't be responsible for the refund since he didn't do the factory settings. I told him that I was acting on the instructions of the Technician but he would would have none of it. He then threw the invoice of Procell in front of me on the table and just walked away. I would just like to know what happened to customer service at your stores and what about the customer is always right since we are responsible for the payment of their salaries. Because without customers there is no Incredible Connections. I don't even want ro mention the rudeness of the store Manager. Can you please follow this up since I've been given the run around by your store but im just a customer who only needed help with a device which was jit even 7 days old.
