How far back on a credit card statement can you go to dispute charges?

Just noticed one from July,07 but Cap one online notice says 90 days. Should I still try?

1. 6 months
2. Try anyway. You should carefully review your statement each month.
3. I would still try. All they can do is say that it is past the 90 days. Or, they may still do.
4. MOST TIME 60 DAYS
