Hey guys! 3 months ago I switched from pre-paid to the $30-per-month plan. At the time there was a $10-off deal going on, meaning if you switched you'd get $10 off your plan per month. So I signed up at a kiosk, and they told me I'd be charged $20 per month. Three months later, I'm still being charged $30 just for the base plan. What's up?
