Losing patience trying sign up for Apple Card

Was getting ready to upgrade iMacs, iPads, etc. for my small business and saw that signing up for the Apple Card would save me 6% through 12/31. So at the Apple Store they told me easy peasy and helped through the process, but then got an email saying unable to verify identity? We tried and talked to people 3 times and no one could tell us what the problem is. Obviously, they must know we have an active Apple ID and credit card attached to iTunes, App Store, etc. and am sure thy can easily find my credit score!

Does anyone know of any magic telephone numbers where we can talk to anyone that knows anything or perhaps even cares. Not the same Apple that I’ve dealt with for years. I’m 73 and have been loyal to Apple products since the beginning, but now really thinking that glam is more important than product and service!
