Move to postpaid and invoice increased at the second month

I recently needed a third line, so decided to move to postpaid, $130 for the 3 lines. I also was offered the Netflix on US promotion, which should add $11 or so to the account. Big was my surprise when this month the account went up almost $25. And of course, calling to the Help line is a test to your patience, as nobody ever answers (unless you have 15 minutes to spare waiting on hold).

Anybody having the same issue? I know the amount is not that bad (14 extra dolars a month won't bankrupt anybody), but is the fact of offering a price and then adding ludicrous fees on top the one that really pisses me off.
