AT&T Internet support

I moved a few years back to my current location and used the move service with att. They installed fiber at my current location and everything has been fine until a few days when I found out my service address is wrong. I called customer support and they refused to change it and wanted me to use new rates and rearrange another installation but I already have everything and when I stated that they hung up the call. I just need my service address changed for a technician can come and fix my broadband issue. I don't understand why they refused. 

ATT is blocking the domain of our website. It was neglected for many years and may had some issues, but we started fresh with Wordress and would like to have this blocking removed. Please advise.

Does anyone have a physical ATT address to return equipment?  I called and texted but they said the only way to return was FEDEX/UPS Stores.  I don't have a car to get to one.

They have been digging fiber optic in my neighborhood, last week they made a hole across the front of my driveway to my neighbors. They came back and put a thin layer of blacktop over it, but not enough now there is a ditch for water in front of my new driveway and all the way across to my neighbor's driveway.
