Account Collections Issue

I contacted Telus after 14 days from signing a contract for a phone line and asked them to terminate my account (November 2024). The first month was already paid. I didn't like the fact that I was immediately asked to pay another bill within two weeks based on a strange time-frame arrangement for payment dates.
I believe the problem Telus has is related to the disconnect they have between the finance department and customer service department. I explained my situation twice to two different agents that I never used the phone line after 14 days of its first month and repeated my request that my act should be viewed as "returning the product", because I was not satisfied with the service, sensing that there would be more problems later. I spent hours talking to the agents who tried to connect me to the financial department but they failed. The computer programs of the financial department continued to charge my account, because it is automatic. Billing is automatic. No one actually looks at whether the phone is active and is being used. They go by what computers tell them. Their computer program decides when to send the account to credit bureau and when to send it to a collection agency. After 5 months I haven't received any assessment on my requests I made to Telus agents, who have absolutely no power and who are also upset that they are not able to solve customer issue during more than one hour chat with them.
I have no time to deal with their humanless business practices. I'll see where it all goes.
