Careless handling and capturing of sensitive personal information.

I purchased a Hisense TV from Hirsch's Hyde Park last year on 26 August. As is typically the case, they offered to activate and process payment for my TV licence with the purchase, which I agreed to. I provided my ID and they generated my invoices and I paid. Just before I got home, I inspected the documents and discovered that they had entered the wrong name and surname on them. I then quickly rushed back to the warehouse, told them they had made an error and they generated new invoices with the correct details (or so I thought). Today, I received a SMS for TV licence renewal and the same incorrect name and surname they entered into the system initially is reflecting there!! What do I call this? Is it *****, carelessness or just plain disrespect for customers? Clearly they did not update the details on their system but changed only the invoices they gave me. This might seem like a simple mistake but it is a breach of the POPI Act, since I asked them to accurately capture my details and they failed to. Also, they have in the process misrepresented my identity to a state entity by assigning my contact details and address to a name which is not mine. Now I must be inconvenienced with trying to sort out their mess after I asked them nicely to fix it over a year ago! This is annoying and they should not offer to activate accounts for customers if they can't capture details correctly.
