I had unlimited plan minutes plus data for 150. dollars because I do no working right now I change my plan to 700 hundred minutes no data per 69 dollars but now I have a bill over 600 hundred dollar per go over minutes. My point is if I have 700 hundred minutes on my plan why they do not cut the service or block the excessive phone call before I get 600 hundred dollar.This the last straw happen many issues before like I change my plan but was no registrant or over charges but the problem is I have contract.
