Billing Issues - multiple calls no resolution

I signed up for Telus internet and cancelled within the allowable window. The sales person who set me up with internet also signed me up for home automation services and shipped a camera and smart home box to my house without my permission. I have been assured my services are all cancelled with Telus but for the past 5 months I have been charged 3.47 on the 27th for some unknown reason. I have called in 4 times and have been assured each time that this charge will stop but again it’s charged this month. When my automation services were cancelled I was charged 125 dollars in equipment fees but I returned the equipment and have been promised by several Telus agents that a refund is on its way but it’s once again its been weeks and no refund. Calling into Telus is such a frustrating experience and I have spent several hours on the phone for this issue that I dread having to call in again to explain this for a 5th time. 

I am not sure how to elevate this issue so I can get this resolved and receive the money I am owed.
