Complaint Review: Sprint

Their customer service is lacking something so obvious... customer service.  I have requested a call back from a supervisor for 2 weeks.  I have requested it 3 times so far.  I think I've done my fair share, and I have since cancelled my lines.  Now they are trying to say that I needed to cancel before my billing close date, yet after a specific unmentioned date.  Now I have a $20 higher ETF for one line... yet I bought both on the same day.  WTF right?  They are so lost in their craziness, they are a lost cause.  Buy a goPhone for something else... Don't get suckered into this pathetic company.
