I bought an unlimited, data and calling plan and phonr..my 3G stoped working, so i called to find out what was wrong..Apperently,there is a "limite" to an "unlimited" plan..i called 10 differant times, just to be transfered to the same automated service, that said "i've exceeded my limite" .. i called and told them this is false advertising and theft by deception, yet they continued to transfer me to the same automated service..EVERYONE Of the representitives could not speak "proper english" and could not understand what i was saying..Not one!
