In a hurry? Citi handles two main types of disputes - charge disputes and ThankYou Points / Rewards disputes. This guide covers both, with the right channel, evidence to provide, and Citi's investigation timeline.

Charge Dispute Reasons

Step 1 - Try the Merchant First

Citi requires you to attempt resolution with the merchant before disputing. Save email correspondence. If they refuse for 7+ days, you have grounds.

Skip if clearly fraudulent.

Step 2 - File via Citi Online or App

  1. Sign in at citi.com or the Citi Mobile app.
  2. Find the transaction in account activity.
  3. Click / tap and select Dispute Transaction.
  4. Pick the dispute reason.
  5. Add description and upload supporting evidence.
  6. Submit.

Provisional credit usually within 1-3 business days.

Step 3 - Phone Disputes for Complex Cases

For unauthorized charges or complex disputes, call 1-800-950-5114 (Citi credit card line) or 1-800-374-9700 (banking). Phone disputes resolve faster.

ThankYou Points Disputes

If ThankYou Points didn't post correctly:

  1. Sign in at thankyou.com or the Citi app.
  2. Find the transaction that should have earned points.
  3. Click Missing Rewards or call 1-800-950-5114.
  4. Provide the transaction date, amount, and merchant - Citi recalculates and credits.

People Also Ask

Other questions our readers commonly ask about this topic:

Is calling Citibank customer service free?

Yes - Citibank customer service is reachable on a toll-free U.S. number that does not charge a per-minute fee. Standard mobile-carrier minutes may apply on metered cellular plans. International callers may pay long-distance charges depending on country and carrier. Visit our Citibank contact page for current toll-free numbers and hours.

How long does it usually take Citibank to resolve an issue like this?

Simple problems (account access, password resets, basic billing questions) typically resolve in a single 10-15 minute call. Complex issues (refund disputes, identity verification, escalated complaints) usually take 3-7 business days because they need supervisor review or document submission. If your case has stalled past 7 business days, escalate to a supervisor or the executive customer service team.

What if Citibank customer service refuses to help me?

First, politely ask to escalate to a supervisor or to the executive customer service team. Most brands have an internal "office of the president" that handles complex complaints. If escalation does not resolve it, file a complaint with the Better Business Bureau (bbb.org), your state Attorney General consumer-protection portal, and - for finance, telecom, or airline issues - the relevant federal agency (CFPB, FCC, or DOT). Our Citibank customer service guide lists the alternate channels.
