I'm struggling to get support from Dell and I'm looking for advice.  I purchased a Vostro last August (2021) with 4-years prepaid ProSupport Plus service.  I reported to Dell on February 8th (2022) that my screen had gone black.  Keyboard lights and fan can be heard but that's it.  Unisys, Dell's contacted support provider for my location, has told me several days running to expect a technician "tomorrow" before 6 PM but no one shows up. 

I have asked both Dell and Unisys to escalate this and to have a manager from each company give me a call.  Crickets.

I have the FedEx airbill number.  I know when the parts were shipped and arrived at the local FedEx distribution center for Unisys to pick up.  I know how many days they sat at FedEx.  I know who finally picked them up, yet "supply chain problems" and "technician shortages" are the excuses given for my being without a work computer for nearly three weeks.

Any suggestions?
