Be aware and get everything in writing related to Telus offers

Sorry you had to go through that. To answer a part of your question, the quote you got does not include taxes. It's also likely that you got proration/partial charges on your first bill along with activation fees that would push it up to a higher amount than what you were advised which is normal for your first bill following change of services/activation. For the rest I'll send you a PM shortly so that I can securely verify your account info and take a look.
