How to elevate a complaint and then cease contract

We switched over from Koodo (which was problem free) well over a year ago.  We switched to the Telus business program for cost savings and for better services, data, etc.   We were told that the switch would be handled for us and that we would not have to do anything, I then deployed with the military and thought nothing of it.  When I returned I eventually found out that only some of my 4 numbers switched over, and that there were extra lines assigned and being charged at Telus.  So for over a year we were being double charged, charged at Koodo even though we were not supposed to be anymore and at Telus for the lines we used and others we were not.  I then called at least 10 times and explained this over and over again.  They switched over 3 of my 4 lines but did not cancel the 2  that we were not using at Telus.  We were being over charged for the lines at Telus and still charged at koodo.  This kept going, support said they would fix it, i would repeat the story and still nothing has happened.  1 line is still at at koodo and I am being charged for 5 lines at Telus but only using 3 and on top of that one of the tech support labelled one line "the wife" which I can say we are not a fan of.

In summary, we have been charged thousands at koodo for services that should have been transferred.  W ehave been charged extra at Telus for lines we do not use and have lost hours of valuable time trying to politely correct this.  We would like the money refunded and this corrected.  I can be contacted privately to confirm the details. Please let me know how to best contact you.
