Serious/Urgent Escalation: No Response

I’m flattened. The start gave significant hope but kept wondering why such a simple issue is dragging. Finally was under the impression the matter was resolved with me getting the offer was promised. Result: Everything thrown aside with an offer via email that I can get anytime. Escalation denying all of my grievances (while putting on a veneer).  I provided the email from a Loyalty Rep that clearly outlines & states the offer she says was never made or never existed. Literally have it in writing. I know the call was recorded. Yet she says none of this ever happened? This is multiple times I have been insinuated as a liar  & had my integrity demeaned. I requested nothing more than her Supervisor, yet she comes back to me going in circles. So I wrote again, I only wish to hear from her Supervisor. I am at my wit's (very sadly, possibly Telus') end. Highly insulting. I'm sincerely reaching for help before I feel the need to contact every Telus Exec (starting w/ CEO; [email protected]) along with Social Media, TV Shows, CRTC, whatever, because this is far beyond just back & forth offers. It is about integrity, both business practices & my own being offended. 3 weeks now, our bill has ballooned because our term is done & something has to give. Telus needs to be aware of all this at the highest levels. I apologize, I don't mean to be salty to anyone, I truly mean good & appreciate your guys' help but this really puts one in a mood. We’re all human & the one thing we seek to vigilantly protect is our integrity. Does anyone have any solid advice here, because as a highly loyal, long-term client for years, I truly do not want to go rogue or go anywhere. I really just want Telus to honor commitments (which I believe is a core component), some meaningful reciprocity & just to be truly seen/heard, especially after all of this would also be great. Thanks in advance.
