I am only on my third bill, but my second bill had somewhere around 160 rollover minutes, and my newest bill shows 59 rollover minutes and according to my statement the date for rollover is my very next billing cycle. I thougth that they stayed for months if they were used. For the record, I haven't been over my 450 minutes yet, so I am not losing them because of usage. Before calling to question them I want to make sure I know what I am talking about. Thanks in advance!
