Error on Mobility bill

I just renewed a contract I owed $106 in early cancellation fees. I owe $310 and bring it back and the new phone was $1,460 so I had to pay tax on that my phone bill is $101 for reference my total bill for my phone was $1016 this absolutely does not make sense and they are saying there's nothing wrong. I wish I could talk to someone local as taxes first of all they charged me $349 our tax rate is 11% hopefully someone can make sense of this for me in the near future. Once my two years is up I'll be canceling my services with Telus as when I renewed this past phone the rep lied to me funny thing is I record every conversation on my phone I called back the next day and they try telling me I couldn't cancel the contract. Once I said I had a recording and they investigated I got a cheap plan and an upgraded iPhone from a 256 to a 516 GB so that's good but now this billing issue and nobody takes accountability. But there is absolutely no way my bill should be $1016
