I have a router supplied by my ISP which has a TR-069 feature and my ISP disabled the ability of controlling that TR-069 (toggling it or configuring it)
My issue is that I am on a limited quota connection (200GB monthly quota), and I started feeling that my ISP is adding fake usage to my quota that I actually don't use but they consider it as used... I then monitored my actual usage using a Mikrotik server and found out that my ISP's website says that I used 200GB of my quota although my actual usage was 114GB only.
So let's get back to the TR-069 part, I started thinking about that thing in my router and if my ISP is using it as a method to steal of my quota or no.
So the question in short is: Can an ISP download data using TR-069? or TR-069 can be used for automatic configuration only?
