I'm not very s very happy customer at this point

We have switched over to Fibre and I thought we would have your normal queries. When we have power outages you cannot just switch off the main plug that feeds the line, but evertime you need to reset the password etc. This is so frustrating and the technical team keeps telling us that the Fibre router cannot handle the outages. I personally feel that's a load of bull dust. Secondly we paying so much more but when I go into our inbox I can't access it. I'm getting excuses but nobody has been able to fix these problems.
