Collection Notice Multiple Account Number (still an active customer with no due)

Received collection Notice for Home Security - Telus Account was incorrect / multiple account generated by mistake at the beginning of service inception.

==== What I believe happened

When my account was being created in 2023, apparently Telus "incorrectly" setup 2 accounts - Lets say Account #A and Account #B.

They later told account #A has been removed (because it should not have existed at all). I got a new contract / agreement, which correctly says single account #B (which is still my current active account, no balance due)

the initial term was for 3 years, which ended in Jan 2026. In Jan 2026 , I happily extended my services with Telus, under Account #B.

However ever since Feb or March I guess, I started getting calls from Collections - General Credit Services and emails from Resolve Financial, stating my details are sent for collections and I should immediately pay 330 $ or I will face legal charges. 

Honestly I ignored the initial calls thinking they are scam / fraudsters, but at some point someone gave me the account number #A as reference on May end.

Now after finally being able to connect to a real agent, who was able to try to track down the details -  she said that this was by ERROR and things are informed to the back office team and that this should be corrected and that my account will be removed from the collection agency list and things like that.

I want someone to look at the details and contact me from Telus - to double triple check and confirm. Also I want this to be a learning for anyone who ends up with 2 contract / account numbers - purely due to an error from Telus side.
