I have been a customer of Sprint for over 10 years and have been very critical of them in the past.
But they have improved immensely regarding billing errors, customer service (though I have not had to speak with them in awhile which is exactly my point) and other areas.
Hard to believe that they are still losing customers at such a high rate.
If someone gave me a choice to switch carriers, I don't see any advantages that the others have over Sprint and only see disadvantages regarding plans, insurance, service coverage, etc.
As of now, I don't have any complaints and that statement coming from me is a big deal
considering a few months ago I was on the phone with Sprint for what amounted to over 100 hours regarding recurring consistent issues.
