I have been overcharged on my Sprint bill for a seasonal standby plan that I would like to end. I have attempted calling my local Sprint store in Abingdon, Maryland to see if they could answer my questions about how to cancel my seasonal standby subscription without being overcharged on my bill. They left me on hold for ** minutes and disconnected me. This really makes me want to jump ship on Sprint entirely, they sure do make AT&AT look really good. NO I do not to have a blind conversation with someone from India, who will not clearly understand that I want to lower my bill, and that I don't need the prorated rate hikes!!!**Because I called intending to have a three minute conversation -I was going to nicely ask why my bill was $* more, and ask for help dealing with the hard details some better time- but they didn't pick up (probably selling more fine print contracts), this leaves me with a sour taste so I am considering going to an entirely different carrier. Sprint can donate all the money they ripped from me to charity - and it will be the last three hours I will take out of my day to clean up and renew my contract with AT&T for simple no-tricks phone service!
