********** EXTENSION OF CONTRACT!!

So my contract ended this month, when I first called last month I was told that there was a new extension made in November, which I was not aware of - No sms, no email, not even a change in the amount I was paying. Since then I have been making calls for escalation and termination of this contract. It was confirmed that is it done, yet to this day it is still active in the system as per the consultants. What are calls recorded for??? I won't allow any further debits on my account. This is unacceptable. Can I be paying the same amount for 4 years without any new device?
