Hi guys,

Last Monday I bought a macbook pro 13' retina using CitiBank credit card at The Mines branch and I didn't know that Challenger is an Easy Payment merchant for Citibank.

When I called CitiBank to apply for Flexi Payment they suggest me an Easy Payment instead but they told me to contact the merchant to do the transaction again for Easy Payment. So I need to know is it possible for me to cancel my last transaction on Monday and do the new transaction for Easy Payment?
