Changed my phone number early August, very quick painless process I thought .Last week I began receiving data over usage texts and email alerts from VZ. Checked my usage on my phone and online, I was only 1/2 way through my data allotment for the month with one week to go. Called they told me I was being prorated over usage charges cause I changed my number in between billing cycles (and Im still only 1/2 way through my data plan )
