so last week called 611 to inquire about adding a 2nd line..we went thru everything and long story short it would only increase my monthly bill by like $30 or so.. so today go to ATT (corp store) and turns out it DOUBLES my monthly bill.. i called 611 today after leaving the store (called 2x) and both reps said the math was right 
what could be up with this?
