Yep, it's exhausting, particularly if you really don't care how it works...just that it Needs to work. When I was younger and less burdened, I thrived over technology and the want to know how everything works. Now I'm too **** busy and uninterested. Heck, I don't even know how to set the dual alarm clock in our bedroom, I have my wife do it. :)
Our internet and house phone (through internet) have been a pain since day one. They advertise the minimum speeds they provide as a "guarantee'...pfft. I complained for over 3 years on my slow speeds, they kept having me bring in my modem and router and upgrade me to the latest and greatest they offer. Thing is, every time i changed it out I would lose the phone. Turns out the guy at the counter handing me the new equipment never checks the box that we have phone, I mean this happens EVERY TIME, even though I tell them to make sure they click all the boxes that we have phone, and I have to call the tech line to straighten it out which takes 45 minutes of being on hold for a 2 second fix on their end. So after 3 years of slow and less than advertised speeds I finally had enough last December and demanded they come to my house and run new wiring or whatever had to be done to fix it or I was dumping them. Low and behold the guy climbed up and checked out the lines and removed something and stuffed it in his pouch. We went in the house and checked again and Boom, I had the 100mps downloads advertised. I looked at the guy and said, You just removed a choke from the feed line didn't you ... he slowly grinned and admitted it. I've spent the 3 months since trying to get a refund of some sort for the last 3 years of nonsense.
Sorry for the rant, but yeah OP, I feel your pain.
