you should talk to the supervisor and let them know that you were promised this earlier.
The wording for the price plans at times can get as tricky as parking signs in NYC. It's only natural to think that unlimited data would include text messages. In the case of the bundled BB plan $59.99 it does but in case of the $19.99 BB add-on it doesn't. Am I the only one that 'ticketed' on the bill because of tricky wording?
Thanks for the advice, that should be true good old fashion loyalty and sticking to their word. That shouldn't be too much to ask for.
