Order Not Received after 1 week plus

My order for a Dell Precision 7780 was placed on Dec 1.  Dell debited my credit card Dec 4.  Fed Ex tracking states the package would arrive Dec 8.  It did not show up.  I have been unable to talk to anyone in customer support.  The Dell Bot is useless.  It can only state that after Dec 4 the computer will "arrive soon".  The FedEx Bot states that the package was received Dec 4 and will arrive Dec 8.  It did not arrive.  Further discussions with the FedEx Bot indicates FedEx has not received the package from Dell (my interpretation).  I have been unable to talk to a Dell Customer Support Agent or a FedEx agent.  I will not do business this way.  Dell will not let me cancel the order, I have to return it.  I do not have the system. I cannot get anyone to tell me what the problem is, so my recourse is to dispute the charge on Dec 4 with my credit card company..  I know where that will go.....wait for XX days.

I have been a Dell business customer for nearly 30 years.  This is no way to run a business....by BOT!
