Vivint Security system upgrade costs and cancellation fees post-migration

So i have Vivint Security.. and while it was operated by vivint it worked amazing...

in 2022 i got the entire system upgraded by vivint just as telus was taking over...  

Since then.. the door bell stopped work.. the door bell camera stopped working.. all my sensors co2, glass break, ect..  also stopped working... then the vivint app stopped working.... i contant vivint, they tell me to contact telus.. so i try and contact telus.. 

after two days i got a call from telus saying they need to upgrade my system to the new standard - and am quoted a bill of $3300 for the upgrade to a system that isnt even 5 years old yet.

So i say i cant afford that and ask them to to cancel the account and come disconnect the system, as if i am paying that much i might as well get a reliable system that will last 5 years.... He then informs me that it is my responsibility to disconnect the system (even though i have no security or electrical skill sets what so ever)..  if telus sends a technician they will charge me $1700 to disconnect the system.... if i dont do either.. they will charge me $2300 for the equipment (even though to my knowledge i already paid vivint the entire system cost when i had it installed.. so why would i be charged for it again?)... so he tells me i might as well pay the $3300.. (oh and the monthly fee was going up by another $20 a month too) and a new contract.

So in short - Telus disables all my sensors, refuses tech support without an extremely pricey upgrade that telus forced and sign a new contract for a higher service fee....or threaten to charge me me between $1700 and $2300 to cancel the service

Way to make me want to stay a Telus Customer...

Anyone else getting scammed like this?

 Looking to raise the $1700 so i can cancel all my telus services..
