Citibank is in hot water, having double-charged some customers for months because of a technical glitch they experienced.  Starting in July, they have been double-charging people because of a problem with an iPad application; the problem was only discovered and fixed in December, according to Citibank spokesman Andrew Brent.

The bank hasn’t wanted to discuss the issue too much, of course, but it appears that about 2% of Citibank transactions that were made through an iPad were counted twice.  Citi has reached out to those clients who were affected and have resolved all problems.

As Brent wrote,

“We take seriously the functionality of our products and services as well as the satisfaction of our clients.”
