I tried to sign up for Simon and had a strange experience.

I tried to sign up with my Citi card, then started having tons of issues with Citi no matter where I shopped. Add to that, DPs here say Citi doesn't like Simon. Oof....

I got my approval for in-store purchase. i wrote CS and asked "how do I change the card I want to use? Should I go through sign up again with the new card?". CSR said "It doesn't matter, use any card you like" which didn't match what I had read here.

Went to mall, tried my Citi card and got declined. Used a different card to finish the purchase. It went through fine.

Later got an email denying my online account. No reason why. I write back to ask why, and ask for reconsideration. Radio silence. They just stopped responding to me. What gives?

Q: anyone seen something like this before?
Q: what should I do next? Reapply with different card?

TIA!
