I have had no service on my phone for 2 weeks

How does one get apple support chat to actually work? I have had no service on my phone for 2 weeks now the only way I can get a hold of support is through chat. I have an iPhone 7 Model A1660 so I know the reason for it is a manufactures error. I have had one chance to talk on the phone with apple support. They said I had to bring it to an apple certified store to repair (since quarantine put shut down apple stores), but the hours for this are during work hours hours I need to be available. The only way for that to be possible because of the phone situation is if I am on at home, I have been trying to contact support for over a week now... 3 days since talking. I need a working phone, right now all that is working is Face-time while I am home which is a way for my work to get a hold of me so I also cant just send in my phone so they can check it, is it really that hard to own up to something apple knows is a manufacturer error, clearly I do not want to buy a new phone right now especially when it is an error on the part of apple.

Sincerely NEED A WORKING PHONE
