Why does Verizon keep charging me for all 30gb of my plan even if I only use 10 or 20gb, but when I go 3gb over the 30 they want an extra $45.00. They better start looking at this practice! I was with AT&T for 14 years before switching to Verizon about 3 years ago. I am beginning to question my judgment. Is anyone else besides me upset with this practice.??
