Exxon/Mobil reports every month. For me, it's between the 25th and 30th of every month. Make sure you have the new card, issued by Citi. The old GE-issued cards are NG.
THANKS COBRA19! I called (again) and miracle of miracles someone who know what they are doing answered the phone... it shpould have been sent to the reporting departiment when I first called in October... "Nancy" has sent it over and it should be on my reports within 30 days! YIPPEE! I know a 1+ year old account reporting will help me.... now if only Citgo will report-LOL.
I always PIF these so the CL helps util - and I never have more than 10% for a balance due.
My Exxon Card isn't reporting either, but I had not used it in about 2 years. I received the new Citi one and used it today to show activity, since they were also good enough to raise my credit limit.
