Apalling customer service

Over the last 7 days I have spent over 25 hours trying to get customer service to address the issue of a slow wireless network at my home. I am a physician and have paid my isp for a broad bandwidth to facilitate rapid downloads of large files through secure vpn sytems. . I called requesting resolution of a slow network (speeds< 100mbps)  Tech support logged into the system and deciphered that the router and satellite needed to be replaced.  Unfortunately only a replacement router was sent resulting in ths problem persisting. Of course the satellite would not be sent out till the old router was received by them...more than a week later still has not come. Service has been irresponsible, appalling in the least.  any attempts to get in touch with a responsible and accountable supervisor has been rejected.  Meanwhile my attempts to get back to work, inthese days of pandemic induced telemedicine have been strangled.   Wonder if any sugeestions in resolving the problems, are there any contact information for the powers that be sitting in their corner offices so that I can speak to them and have the issue taken care of...

Or do I write netgear as a loss and move to Google Nest or alternatives...Appreciate any advise.
