Customer Service Broken Promises - Not being honoured what was offered

I had the same thing happen to us (business account with 6 lines).  We had offers for plans and devices on all 6 lines that were confirmed by phone and email, with us confirming via email to execute the deal officially.   Two days later nothing has happened and we're now told we are out of luck as the deals have expired and they won't honour what we agreed to.  They offered us an inferior plan for alot more money instead, suggesting we had no choice.

To top it all off, after attempting to escalate via the instruction on the Telus website, I was answered by someone from the Phillipines call centre pretending to be an escalations manager.  It was easy enough to discern this to be untrue as she let slip that Telus escalations department can't be reached directly (while simultaneously claiming there is no one besides her to speak with and they can't honor the plan).  I asked her for this by email so it would all be in writing (as so I would have her fill name for record) and she refused.  

Curious to see if Telus responds to our ticket regarding these interactions.  Luckily it's easy enough to port out to other providers (who we have already spoken to) if they don't step up.
