Which usage types are charged to my bill?

Question

Last month I had the following usage type totals for my main cell phone:
Minutes by Usage Type Report
PlanAllow,PromoAllow
8
PlanAllow
289
Overage
40
N&W
18
PlanAllow,CallVM
3
M2MAllow
158
N&W,CallVM
2
PromoAllow,PartAllow,Overage
9
PromoAllow
18
Total
545
The total on my bill was 342 minutes and I can't figure out which types are included in that total.  I was told that any type with 'PlanAllow' or 'Overage' would be included, but that adds up to 329 if I only count the 'PlanAllow' and 'Overage' figures.  If I also include the other types that have 'PlanAllow..' + additional, e.g. 'PlanAllow,PromoAllow', I get 349.  So where does the 342 come from?

Answer 1

Since you've asked, we have the
NATIONWIDE TALK SHARE 1400
Includes:
Monthly Account Access Charge
Monthly Line Access Charge for 3 lines
1400 Shared Monthly Allowance Minutes
Per Minute Rate After Allowance: $0.40/min.  Peak ,  $0.40/min.  Off-Peak
I'm not sure why it would make any difference which plan.  I'm a software developer and typically there are uniform algorithms based upon fields like Usage Type that determine what's included and what's not included in a total.  I'm not sure why Verizon doesn't just add a column in the data they provide that would indicate whether particular call's minutes are included in the bill or not, unless they're trying to obfuscate the numbers so that customers get frustrated in trying to figure out how Verizon calculates the total minutes that can be charged at the exorbitant $0.40/min. rate.
The numbers I've posted were for just one of our three phones and our overages for that month added up to $110.  I had recently reduced our plan from 1400 to 700 minutes, but in doing so I had to give up the Friends and Family program.  With that much overage I really wanted to be able to analyze where the overages were coming from, but based upon the data provided I can't.  I've subsequently increased my plan back to 1400 minutes even though we are usually well under 700.  To Verizon's credit, they were willing to waive the difference of the overage minutes and what it would have cost if I had kept the 1400 plan, but I'd still like to be able to reconcile their provided data and analytic tools to my bills so that we can manage our calling behaviors in a way so that we don't end up paying for an extra 700 minutes per month that we don't use.
