Back to this thread, OP here with an update.
After Chase reinstated my CSR in Sept. 2020, I have successfully applied for 3 more Chase cards.
Chase Freedom
United Quest
Marriott Boundless
I loved 80000 United miles and 60000 Marriott points!
I am still keeping my CSR, but my wife and son closed their CSR due to lack of travel.
My current balance for 4 Chase cards is over $30,000 with combined credit exceeding $120,000.
However, my credit score is down to 680 from 830. I only have Chase cards. Why?
