My husband has a Citi Master Card. Couple months ago we reviewed the charges on the credit card statement and found one of the charges wasn’t authorized. We called the Citi Master card customer service and request a bill/receipt of the charge be mailed to us. We never receive our requested receipt and the charges kept coming on every statement. My husband called Citi Master card customer service again and spoke to a representative, we request to cancel the credit card if this charge keep going through. The representative explained that if it’s a pre-authorized transaction, there’s no way for us to stop it even if the credit card is cancelled. I told my husband to authorize me to speak on his behave and I took over the phone. I asked the representative to repeat what she had previously told my husband so I can make a choice. Her respond was “just ask your husband, I’ve already explained it to him”. I was getting very angry at this point, this is not the type of customer service I have expected. I’ve asked her again if she can repeat it so we can make our choices and she refused. So I’ve asked her to transfer me to a manager on duty, she simply said hold on and hung up on me. We called back right-a-way and got another representative which was much more helpful and I’ve asked her if she can put me through to a manager so I can track down the previous representative. When I spoke to the manager, he apologized for the behaviour and said he’ll follow up with the agent but I never hear back from him. This is by far the worst customer service I’ve received! Up till now the charges are still coming through on our statement and they can’t locate the company that’s charging us.
