[Prices] 2 year, $48 tax inc. price guarantee, has jumped in 2nd month.

The door to door rep that signed me up for their Gigabit service assured me of this price. This is Rogers, the price for the first month was spot on, now on the 2nd month, it has jumped to $54. Did I get bamboozled or can the promised pricing by the rep be made to be honored by Rogers? Edit: Well, after chatting with Rogers, I was told the following, "The promotion on your account is not a contract, but is a discount guarantee for 24 months. The discount will remain on your account for the full 24 month period. It would only be a term with a contract that had a price fix guarantee. Since the majority of customers no longer wanted contracts, Rogers has moved to discount guarantees instead of contracts." The Rep who sold me the service promised me that the price would be $48 tax inc for a 2 year guarantee. That led me to believe that this was protected then from any of the infamous Roger's price hikes that I've read about in other threads.
