I signed up for Verizon on September 26th and my new data starts on the 27th of October. I am on the 2GB single line plan. I used exactly 1306 mb or 1.3 gb to simplify. My phone confirmed this which also keeps track. I was charged $15 overage because they said I went over my allowance. This was due to unbilled data usage which apparently means it was data that came later because Verizon contracts with other towers. So what this all means is I stayed within my data allowance but Verizon rounded my usage to 2 GB and then when they received the data usage from the unfilled contract sites it made me go over. I argued that I will not pay for data thats not accounted for. He had no answer for me. Has anyone else experienced this? And if there are any customer service reps reading is this what happened? Do you guys round data to the GB? Would I have to us less than a GB every month in order to leave that 1 gb buffer in case this happens again? Not a good first impression let me tell you! T-Mobile never pulled this BS. What I used was exactly what I was billed for...
