I have the same problem. Did you write to Samsung about this issue?
I'm sorry to hear you feel this way, @Neo_QLED, but you can use any one of the other available contact methods to chase the callback you were advised of a week ago, and then proceed from there. The same Troubleshooting steps will less likely be provided again if there's a record of them on your previous interaction, and our Support Team will instead focus on the next available steps rather than the same ones you've been through.
If you'd like to contact the Technical Support Team using a different contact method, you can find these here: https://www.samsung.com/uk/support/contact/
