Lack of Service

A few days ago I called the credit card call center to have an amendment done on my credit card.<br> I was told that I need to email certain documents and that the turnaround time is 2 business days.<br> That timeline has since passed.<br> I called the call center today and they told me that there is no feedback and they also said that the email address I was given is incorrect - Now why is that my problem? <br> I left my number for a Team Leader to call me back and obviously I've heard nothing.<br> So what now?
