Agreed to swap to Telus pre-move in with promised discount. Discount not applied.

Hi all. I made the choice to sign up for Telus internet a month before the move to my new place, and I was contacted by Telus a few days offer who offered a mobile plan that was said to be cheaper than my then current carrier Fido, due to a deal/discount my new building has with Telus. I didn't think a connection fee was mentioned either when I asked for any extra fees/costs.

Cut to now and I have a bill coming soon with the 80$ connection fee and no discount--30 dollars more than my old plan. I might swap back immediately if the deal isn't honored as I don't intend on paying this much every month. I tried to submit a dispute form but I only get hit with 'We’re having trouble submitting your bill dispute at the moment. Please try again later.' :( Where do I reach out to get my promotional price back? This is not what was agreed upon. Thank you!
