8 months ago I purchased one time WIFI internet service from AT&T at an airport. Now I realise that I am subscribed to a yearly service paying 20$ a months.

I built web sites all my life for a living so I'm 110% sure that it wasn't very clear that I'm subscribing to a yearly service.

I find AT&T's aproach very deceiving because I opened up a web page designed for that airport and its clear that %90 of the passangers would like to purchase a "one time" service. The default options could have been that way.

This is such a huge disappointment!
