Complaints about Phone Numbers866-240-####

need to call 866-240-9462 (scam you tell me) to collect 8,500,000.00 or it will be turned over to the state

1-866-240-2331 is a legitimate number! This is the number you call to activate your new or replacement Citi Bank Costco Visa card! Make the call. Activate your new or replacement Citi Bank Costco Visa card so you can use your replacement card! Duh!!!!!!!!!

Keeps calling my unlisted, unpublished, home phone number that is also registered on the national "do not call list"

Legitimate Discover card fraud detection alert line that verifies potential fraudulent usage of your card and can cancel/replace card if fraud did occur.

Said hang on while we connect you then immediately said all lines were busy and to call them back I didn't call them they called me I'm not calling
