Apple Card - not receiving emails

Anyone else have issues receiving emailed communications from Goldman Sachs/Apple card? My current email address is in the format of my first name underscore my last name @ hotmail.com .... apparently the system does not like the underscore .... I have tried EVERYTHING from calling multiple times, chatting, and even reached out to hotmail. All say there should be no reason I am not receiving the emails. This is quite a problem as I have had a couple of chargeback purchases that I literally lost because I did not "reply" to a request in time so they sided with the bogus merchant plus I literally never receive statements. I did reach one rep who indicated it is kind of a known that some "formats" in email addresses can cause issues such as this and that I would have to 1) change my apple id (which is this email address) 2) close my current apple card 3) reapply for a new card .... the reps always just change me to "paper" but even then, by the time I receive the paper communications it's been too late.

I could really use some guidance if anyone knows how to rectify this.
