Tried for an increase via chat on day 90 (12/21) after my last CLI, Denied.
I thought I would give it another go today (2 days later) for fun and boom $3500->$7500 (+$4,000). Went with the luv button this time as opposed to chat and asked for $7500 instead of $10k on last attempt (Did I leave some on the table?).
Tried for increases on my other 2 synchrony cards (76, Chevron) and denied.They haven't seen much use at all, so I am not suprised I guess.
Congratulations on your CLI!
Congrats on your CLI!
