my cell phone bill used to be $250'ish every month until i called them about upgrading my phone, the woman took a look at my plan and said "ma'am, you have a large phone bill...if you change your plan to [insert plan name here], we'll just charge you $5 for every 100 minutes you go over instead of $0.30 a min."
since then, my cell phone is back down to $120
but they raped me with charges for about a year
edit: oh ya, this is Sprint btw lol
