Dell refuses to send the replacement system. 4 orders were created for the replacement and each was cancelled.

Shortly after I received my new Dell laptop, a technical problem appeared and Dell promised to send me a replacement model. The laptop is still under warranty.

On April 10, 2023, a Dell employee contacted me about the replacement of my Inspiron 14 Plus.
On April 13, 2023, he created the order for the replacement system. After a few days, it was cancelled. I wrote him an email and on April 17, he created a new order, but it was cancelled again after a few days. I wrote again and a week passed until he replied that Dell had issues with the order and created a new one on April 27. This order has been cancelled again.
I wrote a long complaint email to the employee, but still have not received a reply from him. In the Dell Technical Support chat I got an answer, and a new order was created, on 4 May. And what to expect? Now this order is also cancelled.

I am VERY disappointed in the work of the Dell Support, I have been waiting for my replacement system for over 3 weeks and 4 times the order has been cancelled! What should I do? Are there higher authorities in Dell that I can contact about this incompetent support?
