C3700 Firmware Update

I understand that the Tech does not push the firmware updates, however the issue I described relates to the router reverting back to factory defaults without My intervention.  The ISP Tech indicated they did not push out update, and I certainly do not have the flash image to perform the update Myself, so the point I was making was that either the Tech was unaware of an update process inside the ISP or the update was pushed by unknown actor, or possibly even no flash was pushed at all, and  might imply a breach in the products security, and hence they left it freshy tainted for me to see.  The unit is not an ISP provided unit, as I purchased the unit and initally setup the config and passwords and such.  So finding the unit defaulted to factory settings is a real cause of concern.  Imagine if it was your device on your LAN and the ISP indicated they performed no intervention.  Would you have any confidence is the security of the device?
