Phone Rep Did Not Apply Promo Code Discounts

I initially signed up online using a promo code offer Telus sent me by mail and was having an issue activating my device and transferring my number from my previous provider.

I called in to inquire about the order and discussed the issue with a rep for nearly 2 hours. In the end they got me signed up, but after checking my account I see that despite saying they were signing me up for the promotional plan ($45 after all discounts), they have just signed me up for the regular plan ($60 after auto payment discount) without the full discounts promised in the Telus mailer. The phone rep assured me he was applying the promo code the same as online.

I believe that what the rep did is cancel my pending order and start a new one (hopefully not to claim the sale/commission), and now the system is not making me eligible as the offer was for first line added to an existing home services account. Since he cancelled my order and created a new one, this is now not the "first order" on the account.

I only have 15 days to cancel no charge so I need to sort this out ASAP, but the second rep I called said they cannot add the discount and that they will look into modifying my home services account to add an equivalent discount there but this will take 30 days. 

To be clear, this promotional offer was for the discount to apply directly to the mobile plan not to the home services plan. I simply want to be given what Telus offered me. If I had known it would be this much trouble I would have thrown the offer in the recycling and stuck with my old provider.

Does anyone know who at Telus can fix this? I'd be happy to stick with the plan if they gave me the price on the mailer.
