Mine has been until about a week ago - now have no idea what is the issue and cannot get in touch with Rad support. NO SUPPORT - very concerning

I have been trying to get support for several days. I have sent 2 emails. I finally got a standard reply the last email sent asking to describe my problem which I had described in the first email.  Might I add that I had called for days before the email.  This is so not like the support which I had received in the past.  I have bought 4 bikes from Rad and numerous accessories.  I will not purchase in the future nor recommend Rad until it changes.  Meanwhile, what am I to do about this issue? I live in an area that the bike shops have very little experience with e-bikes much less Rads UGH!  I will probably have to drive over 100 miles to the one shop that I found that says they work on Rads.   This is a RadCity 5 plus that has the issue now.
