Internet service contract expiration arbitrarily changed by TELUS

I signed up in October 2023 for what was then called "office" internet, with a 3 year contract (expiring October 2026).  At the end of 2024 we moved, so I started inquiring about moving my existing service to our new home.

After several back and forth emails and phone calls, I was told that the move would not be a problem, since the same fibre 1G service was available at my new location, and that the existing static IP address could be kept as well.  

On the date scheduled the TELUS installer came to connect the service but, surprise, I was told me that he was not aware of this been a continuation of a business plan, but a new home installation.  After a couple of internal call on the tech part, my service was enabled (also got a new account number). 

After several calls with tech support, my static IP was as well. Fast forward one year, and I contacted TELUS to inquire about possibly switching to home service ASAP, or when my contract expires, and also ask about TELUS repeatedly overcharging my account, even though a valid CC has been on file according to the MyTelus website.

In the course of multiple phone conversations, I am told that my contract is now set to expire in November 2027.  I kept asking the reason why this could have happened, since my original contract duration was 3 years, not 4.

Eventually the rep tells me that the reason for the change was the move itself: according to them there was simply no way the contract could not have been "reset" by moving, even though this was never pointed out to me ever during me asking about moving my service

I asked to be called back by a supervisor, and she confirmed that the move was the one and only reason for this.  There is NOTHING they can do, except moving me to monthly renewals, which effectively doubles my costs for the next 2 years.

I've been with TELUS since the 90s, copper, DSL and finally fibre.  I just wanted to ask if anyone knows if the story I've been told makes any sense.
