increase in bill with no change in service

[bcondon]

I have autopay set up for bill payment. Currently wondering why my bill increased by approximately $12 for the last few months without any notification or without any change in service.

@bcondon , please look at your payment history carefully to see where the "extra costs" are coming from.  Each cost and reward item are listed as separate line items there.  It should be easy to see where the changes took place.

Were you on a promotion plan by chance? In the past they had $10 off for 6 months.

Did you refer some friends or family ?  PM did a clean up of awards so if accounts were no longer active then you would lose the award.
